1.0 FACILITY AND SWPPP OVERVIEW

The Indeck Alexandria facility is an electric generating station comprised of a wood-fired boiler (traveling grate stoker, Zurn design) and auxiliary equipment including a steam turbine, hydraulic loading systems, transformers, wood chip piles, a two-celled cooling tower, a diesel fire pump and a standby diesel generator. The rated electric output of the main boiler is approximately 16 MW. Operation commenced in October, 2009.

The Station is located in the Town of Alexandria, Grafton County, New Hampshire, on a 27-acre site bounded by the Smith River, adjacent private properties and the Smith River Road (aka Old Route 104). The portion of the site used for power plant operations is approximately 7 ½ acres. The Smith River, which runs directly adjacent to the west of the facility, drains to the Pemigewasset Watershed (EPA Watershed #01070001).

The portion of the Smith River is classified as an Impaired Water due to pH levels and elevated levels of mercury2. EPA and NHDES have established a mercury “total maximum daily load” (TMDL) value for this watershed, known as the Northeast Regional Mercury TMDL. In New Hampshire, this corresponds to 0.3 ppm mercury in fish tissue3. Monitoring and testing details are provided in Section 3 of this Plan.

A site plan depicting stormwater conveyance systems is included within Appendix A of this Plan, and additional details are provided in the following sections. In general, the facility consists of a main building (containing offices and the electric generating equipment), wood chip piles, a wood chip delivery/processing/conveyance system, cooling towers, a drum storage building, two process water ponds and a stormwater pond. The facility’s stormwater discharge to the Smith River environment (via one point-source outfall) is regulated under EPA’s National Pollutant Discharge Elimination System (NPDES) program – specifically, the 2015 Multi-Sector General Permit (MSGP).

Indeck Alexandria is subject to Sections 1-7 of the 2015 MSGP, as well as Section 8, Industrial Sector O (Steam Electric Generating Facilities). The facility is classified under SIC Code #4911 (electric generating facilities) and the facility’s electric generating system consists of a wood fired steam boiler and steam turbine which meets the applicability requirements of Industrial Sector O. Section 5 of the 2015 MSGP requires preparation of a Stormwater Pollution Prevention Plan (SWPPP). This Plan is compliant with the SWPPP requirements therein, as detailed in Table 1-1.

Note: Although the facility conducts minor ancillary processes on site to support the electric generation process (e.g., storage of a limited number of whole logs), it has not been assigned a SIC code other than 4911 (electric generation) by any U.S. government agency.

2.0 STORMWATER SYSTEM AND CONTROLS

The stormwater conveyance systems at the facility are as follows:

The northern edge of the facility drains to two trenches, one on either side of the main access road. The endpoints of these trenches are two culverts that traverse underneath the paved roadway and parking lot. The two culverts converge into one outfall (Outfall 002) that empties to the Smith River.

Most of the Facility grounds (excluding the northern edge) are graded such that stormwater flows to trenches encircling the perimeter of the facility. The trenches ultimately drain to a large stormwater retention pond at the southern end of the property. This pond permeates into the ground and drains to ground water, therefore it is not a stormwater outfall subject to the MSGP per EPA’s guidance.

A stormwater diagram is provided in Appendix A. There have been no significant spills or leaks in the three years preceding this Plan.

2.1 Industrial Activities Exposed to Stormwater

Table 2-1 details the facility’s industrial activities that may be exposed to stormwater, as well as the corresponding pollutants and control measures. Significant spills and leaks may occur at the following areas (see Appendix A for locations):

Hydraulic Truck Dumpers (tanks and piping) Chemical and Oil Delivery Areas 34.5 kV and 4160 V Transformers (enclosed by containment berm) Vehicle Refueling Area

Many facility processes (e.g., storage of ammonia, sulfuric acid or boiler treatment chemicals) are not exposed to stormwater and are therefore not discussed in this Plan. Other than the wood chip pile, no general materials (e.g., process supplies) are stored or stockpiled in areas exposed to stormwater. Furthermore, the site does not contain any landfills, scrap yards, surface impoundments, open dumps, or general refuse sites that may be exposed to stormwater.

The oil storage units 55-gallons or larger (including the transformers, diesel tanks, hydraulic tanks and drums) are also a component of the facility’s Spill Prevention, Control and Countermeasure (SPCC) Plan, implemented separately under 40 CFR 112, which provides spill prevention practices including a delivery procedure, secondary containment drainage procedure, inspections, testing, training and other measures. Furthermore, NH DES regulation Env-Or 306.05 specifies that stormwater that is contaminated with oil (i.e., in secondary containment areas) shall be discharged to an enclosed container for transport to an authorized location.

With regard to process water, Indeck Alexandria is designed to be a “zero discharge facility”. It is not connected to a municipal water system. The process water is initially delivered as deionized

Indeck Energy – Alexandria, LLC SWPPP 10

water or drawn from the river. Water entering any process drains or floor drains proceeds to the outdoor low level waste pond, and is then routed to the cooling tower and returned to the process system (or dissipated as steam). If process water must be removed due to an unusual event, it is collected by a contractor. The facility’s potable water is drawn from wells, and sanitary waste is discharged to an onsite septic tank. It should also be noted that the facility has a 8,000-gallon aqueous ammonia tank and a 6,000-gallon sulfuric acid tank, however, these are located indoors and are not exposed to stormwater.

2.2 Non-Stormwater Discharges

The following non-stormwater discharges are permitted under Section 1.1.3 of the 2015 MSGP:

Discharges from emergency/unplanned fire-fighting activities; Fire hydrant flushings; Potable water, including water line flushings; Uncontaminated condensate from air conditioners, coolers/chillers, and other compressors

and from the outside storage of refrigerated gases or liquids; Irrigation drainage; Landscape watering provided all pesticides, herbicides, and fertilizers have been applied in

accordance with the approved labeling; Pavement wash waters where no detergents or hazardous cleaning products are used (e.g.,

bleach, hydrofluoric acid, muriatic acid, sodium hydroxide, nonylphenols), and the wash waters do not come into contact with oil and grease deposits, sources of pollutants associated with industrial activities, or any other toxic or hazardous materials, unless residues are first cleaned up using dry clean-up methods (e.g., applying absorbent materials and sweeping, using hydrophobic mops/rags) and the facility has implemented appropriate control measures to minimize discharges of mobilized solids and other pollutants (e.g., filtration, detention; settlement);

Routine external building washdown / power wash water that does not use detergents or hazardous cleaning products (e.g., those containing bleach, hydrofluoric acid, muriatic acid, sodium hydroxide, nonylphenols);

Uncontaminated ground water or spring water; Foundation or footing drains where flows are not contaminated with process materials; and Incidental windblown mist from cooling towers that collects on rooftops or adjacent

portions of the facility, but not intentional discharges from the cooling tower (e.g., “piped” cooling tower blowdown; drains).

2.3 Salt Storage

A salt/sand mixture pile, used for de-icing, is kept within a designated “dome tent” structure (covered and enclosed on three sides) at the east end of the site, as shown in Appendix A. It is only used and replenished during icy conditions. The mixture is delivered by truck and transferred within the facility by a Bobcat loader or similar equipment. If salt is inadvertently exposed to stormwater, runoff may enter the perimeter trench system and lead to Outfall 002.

Indeck Energy – Alexandria, LLC SWPPP 11

Table 2-1 Industrial Activities Potentially Exposed to Stormwater

Industrial Activity Potential Pollutant(s) Control Procedures

Wood Chip Deliveries

Total Suspended Solids (TSS) (coarse)

Hydraulic Oil (from truck dumping tanks and

piping systems)

Misc. vehicle oil and fluids

Other pollutants may be present in wood at

trace levels – see wood ash analysis in

Appendix C. The wood chips have

essentially the same constituents as the

surrounding wooded environment.

Wood chips are stored on paved, impervious surfaces.

Conveyors and processing areas are covered. A stormwater

trench runs along the perimeter of the paved area to collect

runoff, and the trench terminates at a stormwater pond in a

wooded area at the south end of the facility. Fabric filters

are laid across the stormwater trench at selected locations

to collect dust.

Hydraulic Oil is stored within weatherproof tanks which sit

upon metal drip pans. The area is inspected for oil leaks on

a daily basis. Storm water is removed from the pans only

after visual inspection indicates there is no oil

contamination.

Whole logs are stored in piles in a designated area outside

the main fence line at the southern end of the facility near

the stormwater pond, which would typically capture any

stormwater runoff from the log piles.

Wood-bound pollutants are shown by analysis to be within

allowable trace levels by state regulations.

The following pollutants may be present at

low levels (e.g., from process chemicals or

boiler water treatment):

ammonia, sulfuric acid, Drewamine 1791

(morpholine), Drewphos (Phosphate and

Sodium Hydroxide, Drewplex ( Sodium

Chloride), diesel fuel, lubrication oil,

hydraulic oil

Pond has an impervious liner and accepts water from the

facility’s process drains and floor drains. Contents of pond

are routed to cooling towers (which may then be emitted to

the air as vapor) – there is no stormwater runoff.

Waste Water Pond for

Quenching Total Suspended Solids (TSS) (coarse)

Stormwater in the immediate area is graded toward the

trenches which lead to the stormwater retention pond. The

Waste Water pond accepts blow down water from the

Scrubber. This Waste Water is trucked off-site by a

contractor. There is no stormwater runoff.

Salt/Sand Deliveries Salt

Total Suspended Solids (TSS) (coarse)

Misc. vehicle oil and fluids

The salt/sand pile is kept within a designated “dome tent”

structure (covered and enclosed on three sides). It is only

used and replenished during icy conditions. Runoff may

enter the perimeter trench system and lead to either the

retention pond or Outfall # 002.

Salt/Sand Spreading

Indeck Energy – Alexandria, LLC SWPPP 13

Transformer Maintenance

and Operation Transformer Oil

Transformers are closed, weatherproof systems. Partial

secondary containment, with a capacity of several hundred

gallons, is provided by concrete berms. Transformers are

inspected for leaks on a daily basis and would have

immediate and obvious effects if there were a leak. Storm

water is pumped out of the berms only after visual

inspection indicates there is no oil contamination. Any

maintenance is conducted manually by personnel familiar

with the equipment.

In the event of a spill, runoff may enter Outfall #002 or

proceed westward, downhill toward the Smith River.

Fire Pump Tank Deliveries

Diesel Fuel Oil

Lubricating Oil

Misc. vehicle oil and fluids

Deliveries take place on paved, impervious surfaces

directly outside the receiving tank. Deliveries are

conducted in accordance with SPCC procedures to

minimize the risk of spills. The storage tanks are indoor or

fully enclosed.

Any spills or runoff would follow paved ground slopes to

the trench system and to the storm water retention pond.

The main parking area is graded toward the main building,

away from the stormwater perimeter conveyance system.

Furthermore, airborne dust is drawn indoors to process

areas by negative suction. Any vehicle maintenance takes

place indoors.

Some runoff may enter the northern stormwater collection

trenches which proceed to Outfall #002.

Vehicle Refueling Diesel Fuel Oil

The diesel storage tank is inside a containment basin and

also within a lean-to structure (covered and enclosed on

three sides) The fueling is performed manually by facility

personnel, and fuel usage is tracked with a gauge.

Any spills or runoff would follow the eastern perimeter

trench to the stormwater retention pond.

2.4 Endangered Species Determination

A review of the U.S. Fish and Wildlife Services (FWS) tool at http://ecos.fws.gov/ipac/ indicated that one threatened species, the Northern Long-Eared Bat, may exist in proximity to the facility. This is a non-aquatic (terrestrial) species which would not feasibly be affected by the stormwater discharge. Furthermore, no listed critical habitats are located within the affected area. A review of U.S. National Marine Fisheries Service (NMFS) maps at http://www.nmfs.noaa.gov/pr/species/criticalhabitat.htm has also indicated that the facility is not in proximity to any NMFS-listed species.

This information was submitted to U.S. EPA, who subsequently confirmed on Aug. 10, 2015 that the facility is eligible for coverage under the 2015 MSGP according to “Criterion A” with regard to endangered species protection (no listed species in the action area). A copy of this correspondence is provided in Appendix H of this Plan.

2.5 Historic Properties Determination

Indeck Energy – Alexandria, LLC has previously determined under the 2008 MSGP that there have been no impacts on historic properties. The 2015 MSGP represents a renewal of prior coverage without any relevant changes in operations (including no subsurface work), and the facility therefore has no potential to have an effect on historic properties. The facility is therefore eligible for 2015 MSGP coverage under “Criterion A” for historic properties: “Your stormwater discharges and allowable non-stormwater discharges do not have the potential to have an effect on historic properties and you are not constructing or installing new stormwater control measures on your site that cause subsurface disturbance.”

2.6 Infiltration Best Management Practices

The only significant on-site stormwater infiltration occurs at the stormwater retention pond at the south of the facility. As shown in Appendix A, most of the Facility grounds (excluding the northern edge) are graded such that stormwater flows to trenches encircling the perimeter of the facility, which ultimately drain to the retention pond. This pond permeates into the ground and drains to ground water. Any dust that may reach the pond would primarily come from the wood chip piles on site, and would have essentially the same characteristics as the surrounding wooded environment, and therefore not create a condition of pollution.

The infiltration Best Management Practices (BMPs) primarily consist of perimeter trench maintenance to minimize particulate matter reaching the pond. As stated within Table 2-1, this includes usage of fabric filters which will be replaced as required. It is also verified that drainage is occurring as expected in order to prevent mosquito breeding; and that there is no evidence of industrial pollutants reaching the pond.

The above BMPs are verified by monthly visual inspections (Section 3.3 of this SWPPP; records and a template form are kept in Appendix D). Inspections, maintenance and

Indeck Energy – Alexandria, LLC SWPPP 18

corrective actions are conducted under the direction of Bryan Coutu, Plant Manager. If required, corrective actions are performed consistent with Section 3.8 of this Plan.

A condition of “no exposure” should always exist for the infiltrated stormwater at the pond. In the event that a certification of no exposure can no longer be made, then the infiltration must cease for that portion of the runoff or the discharge must be permitted or registered as appropriate. The following may be required:

Infiltration BMP that meets the definition of a Class V well or that infiltrates stormwater via a subsurface structure (i.e. concrete chambers, dry well, leach field, etc.) will need an underground injection control (UIC) registration from NHDES; and

Permitting as a groundwater discharge as required in Env-Wq 402, if the stormwater will or may contain regulated contaminants.

The SWPPP must be modified immediately if new infiltration BMPs are proposed or if existing infiltration BMPs will cease.

Notify the NHDES Groundwater Discharge Permit Coordinator immediately if any infiltration BMP may need to be permitted or registered during the permit term. Notify the NHDES Wastewater Engineering Bureau immediately of any plans to discharge any new non-stormwater discharges during the permit term (excluding the allowable non-stormwater discharges listed in Section 2.2.) Any such notifications must be addressed to: NH Department of Environmental Services Wastewater Engineering Bureau, Permits & Compliance Section P.O. Box 95 Concord, NH 03302-0095.

2.7 General Facility Maintenance

Good housekeeping practices are implemented to keep the site clean and well organized. An operator makes regular tours (every two hours during business hours) to clears away indoor and outdoor waste, garbage and debris. Materials are stored in appropriate containers and trash bins are kept shut. No polymers and/or other chemical treatments as part of erosion or sediment controls.

The facility’s Spill Prevention, Control and Countermeasure (SPCC) Plan, implemented separately under 40 CFR 112, provides a number of facility-wide good housekeeping procedures, including but not limited to the following topics:

Delivery Vehicles Oil/Chemical Loading and Unloading Areas Storage Tanks Oil-Bearing Equipment in Switchyards Spill Reduction Measures

Indeck Energy – Alexandria, LLC SWPPP 19

The facility also maintains separate procedures for (e.g., truck dumping and ash loading). Finally, additional good housekeeping (e.g., inspections of ponds and trash collection) and preventive maintenance inspections are embedded within the monthly inspection form included with this SWPPP (Section 3.3 / Appendix D).

2.8 Training

Training on pertinent aspects of this Plan is as directed in the facility’s Spill Prevention, Control and Countermeasure (SPCC) Plan, implemented separately. As stated therein, onsite discharge prevention training is provided to each employee (except for admin assistants) each year. This also serves as a spill prevention meeting where any recent events are discussed, as well as the required training under this Stormwater Pollution Prevention Plan. Training records are maintained in employees’ personnel files.

3.1 Evaluation for Unauthorized Non-Stormwater Discharges

On August 14, 2015, an evaluation for unauthorized non-stormwater discharges was conducted by Bryan Coutu, Plant Manager. This evaluation was conducted during dry weather conditions while the electric generation process was in operation. The areas shown on the non-stormwater inspection form (Appendix I) were visually inspected.

This evaluation did not observe any non-stormwater discharges to be occurring, therefore no additional actions were deemed necessary as a result of the inspection. This concurs with the facility’s operating experience and engineering judgment, which is that no non-stormwater discharges are feasible during normal operations, other than those specifically permitted under the 2015 MSGP (listed in Section 2.2 of this Plan).

3.2 Notice of Intent

A Notice of Intent for the 2015 MSGP is being submitted per EPA’s instructions using EPA’s electronic NPDES eReporting tool (NeT). A copy of the NOI, EPA’s acknowledgment letter and any other correspondence will be kept on file with Appendix B of this Plan.

3.3 Monthly Facility Inspections

Facility inspections must be conducted at least once each calendar month, during normal operating hours4. At least once each calendar year, the inspection must be conducted during a period when a stormwater discharge is occurring. Inspections must be performed by a member of the stormwater pollution prevention team.

A site-specific inspection form is provided in Appendix D of this Plan, which lists the facility’s stormwater control measures, activities that may be exposed to stormwater and other information required by the 2015 MSGP. The form will be completed by the inspector and completed forms will also be stored in Appendix D of this Plan. Any corrective action required as a result of a monthly facility inspection must be performed consistent with Section 3.8 of this Plan.

In general, the inspector must examine or look out for the following:

Industrial materials, residue or trash that may have or could come into contact with stormwater;

Leaks or spills from industrial equipment, drums, tanks and other containers; Offsite tracking of industrial or waste materials, or sediment where vehicles enter or

exit the site; Tracking or blowing of raw, final or waste materials from areas of no exposure to

exposed areas;

4 Although routine facility inspections are generally performed quarterly under the 2015 MSGP,

Industrial Sector O (Steam Electric Generation) specifically requires a monthly inspection.

Indeck Energy – Alexandria, LLC SWPPP 22

Control measures needing replacement, maintenance or repair; Loading or unloading areas, switchyards, fueling areas, bulk storage areas, ash

handling areas, areas adjacent to disposal ponds and landfills, maintenance areas, liquid storage tanks, and long term and short term material storage areas.

Inspectors must also consider the results of visual and analytical monitoring (if any) for the past year when planning and conducting inspections.

3.4 Quarterly Stormwater Sampling

Once per quarter, a stormwater discharge sample will be collected from Outfall 002 in order to conduct the visual inspections (Section 3.4.1) and benchmark monitoring (Section 3.4.2) required under the 2015 MSGP. Sampling requirements begin in the first full quarter following either September 2, 2015 or the date of discharge authorization, whichever date comes later. These samples must be collected in such a manner that the samples are representative of the stormwater discharge. At the facility’s discretion, additional samples may be taken during separate runoff events and used to determine the average benchmark parameter concentration for facility discharges.

All required monitoring must be performed on a storm event that results in an actual discharge (“measurable storm event”) that follows the preceding measurable storm event by at least 72 hours (three days). The 72-hour (3-day) storm interval does not apply if the facility is able to document that less than a 72-hour (3-day) interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring must be performed at a time when a measurable discharge occurs.

For each monitoring event, except snowmelt monitoring, the facility must identify the date and duration (in hours) of the rainfall event, rainfall total (in inches) for that rainfall event, and time (in days) since the previous measurable storm event. For snowmelt monitoring, the facility must identify the date of the sampling event.

Exceptions to quarterly sampling are shown below. The required total number of samples must still be collected. The facility must also report a “no data” or “NODI” code within EPA’s electronic NetDMR system for any of the regular reporting periods that there was no monitoring.

Adverse Weather Conditions: When adverse weather conditions prevent the collection of samples during the quarter, the facility must take a substitute sample during the next qualifying storm event. Documentation of the rationale for no visual assessment for the quarter must be included with the SWPPP records. Adverse conditions are those that are dangerous or create inaccessibility for personnel, such as local flooding, high winds, electrical storms, or situations that otherwise make sampling impractical, such as extended frozen conditions.

Indeck Energy – Alexandria, LLC SWPPP 23

Climates with Irregular Stormwater Runoff: If freezing conditions exist that prevent runoff from occurring for extended periods, then samples for the quarterly visual assessments may be distributed during seasons when precipitation runoff occurs.

Areas Subject to Snow: In areas subject to snow, at least one quarterly visual assessment must capture snowmelt discharge, taking into account the exception described above for climates with irregular stormwater runoff.

3.4.1 Quarterly Visual Inspections

The visual assessment must be made of a sample in a clean, colorless glass or plastic container, and examined in a well-lit area. The inspector must visually inspect or observe the sample for the following water quality characteristics:

Color Odor Clarity (diminished) Floating solids Settled solids Suspended solids Foam Oil sheen; and Other obvious indicators of stormwater pollution.

The results of the visual assessments will be documented in Appendix E of this Plan. A blank form is also provided in Appendix E.

The visual assessment findings are not submitted to EPA, unless specifically requested to do so. However, the findings are summarized in the annual report (see Section 3.6). Whenever the visual assessment shows evidence of stormwater pollution, corrective action procedures are initiated as described in Section 3.8 of this Plan.

3.4.2 Benchmark Monitoring

Industrial Sector O of the 2015 MSGP specifies a benchmark of 1.0 mg/L of total iron for the facility’s stormwater discharges at Outfall 002. Benchmark monitoring must be conducted quarterly for the first four full quarters of permit coverage, commencing no earlier than September 2, 2015, in order to determine the overall effectiveness of control measures. The benchmark concentrations are not effluent limitations; a benchmark exceedance, therefore, is not a permit violation. However, if corrective action is required as a result of a benchmark exceedance, failure to conduct required corrective action is a permit violation. Results must be submitted to EPA within 30 days using EPA’s electronic NetDMR system. Benchmark monitoring records will also be stored in Appendix F of this SWPPP.

Indeck Energy – Alexandria, LLC SWPPP 24

40 CFR 136 indicates that any of the following test methods may be used to test for Total Iron levels:

EPA Test Method 200.5, 200.7, 200.8, or 200.9 Standard Test Method 3111 B-1999, 3111 C-1999, 3113 B-2004, 3120 B-1999,

Open File Report 98-165, Methods of Analysis by the U.S. Geological Survey National Water Quality Laboratory

After collection of four quarterly samples, if the average of the four monitoring values for any parameter does not exceed the benchmark, the facility has fulfilled the monitoring requirements for that parameter for the permit term. After collection of four quarterly samples, if the average of the four monitoring values exceeds the benchmark, the facility must, in accordance with Section 3.8 of this Plan, review the selection, design, installation, and implementation of the control measures to determine if modifications are necessary to meet the effluent limits in this permit, and either:

Make the necessary modifications and continue quarterly monitoring until the facility has completed four additional quarters of monitoring for which the average does not exceed the benchmark; or

Make a determination that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice, in which case the facility must continue monitoring once per year. The facility must also document the rationale for concluding that no further pollutant reductions are achievable, and retain all records related to this documentation with the SWPPP.

If an exceedance of the four quarter average is mathematically certain, review the control measures and perform any required corrective action immediately (or document why no corrective action is required), per Section 3.8 of this Plan, without waiting for the full four quarters of monitoring data,. If after modifying the control measures and conducting four additional quarters of monitoring, the average still exceeds the benchmark (or if an

Indeck Energy – Alexandria, LLC SWPPP 25

exceedance of the benchmark by the four quarter average is mathematically certain prior to conducting the full four additional quarters of monitoring), the facility must again review the control measures and take one of the actions above.

Natural background pollutant levels: If it is determined that exceedance of the benchmark is attributable solely to the presence of that pollutant in the natural background, the facility is not required to perform corrective action or additional benchmark monitoring provided that:

The average concentration of the benchmark monitoring results is less than or equal to the concentration of that pollutant in the natural background; and

The facility documents and maintains with this SWPPP, the supporting rationale for concluding that benchmark exceedances are in fact attributable solely to natural background pollutant levels. The facility must include in the supporting rationale any data previously collected (including literature studies) that describe the levels of natural background pollutants in the stormwater discharge.

Natural background pollutants are those substances that are naturally occurring in soils or ground water. Natural background pollutants do not include legacy pollutants from earlier activity on site, or pollutants in run-on from neighboring sources which are not naturally occurring, such as other industrial sites or roadways. However, the EPA Regional Office may determine that the facility is eligible to discontinue monitoring for pollutants that occur solely from run-on sources.

Blank forms to document general corrective actions, corrective maintenance and benchmark monitoring exceedances are provided in Appendix J of this Plan.

3.5 Annual Impaired Waters Monitoring

The portion of the Smith River to which the facility discharges is designated by EPA as Impaired for the following parameters:

Table 3-2 Receiving Water Impairment

Parameter Total Maximum Daily Load (TMDL)

Mercury 0.3 ppm in fish tissue (outfall monitoring not required)

pH No TMDL established (outfall monitoring required annually)

Indeck Energy – Alexandria, LLC SWPPP 26

EPA’s reference for this water body is available at: http://ofmpub.epa.gov/tmdl_waters10/attains_waterbody.control?p_list_id=NHRIV700010702-22&p_cycle=2010

The facility must monitor all pollutants for which the waterbody is impaired and for which a standard analytical method exists (see 40 CFR Part 136) once per year at Outfall 002 discharging stormwater to impaired waters without an EPA-approved or established TMDL. Discharges to impaired waters with an EPA-approved or established TMDL are not required unless specifically required by EPA.

Therefore, beginning in the first full quarter following September 2, 2015 or the date of discharge authorization, whichever date comes later, the facility must monitor pH levels at Outfall 002 once per year (mercury monitoring is not required.)

Results must be submitted to EPA within 30 days using EPA’s electronic NetDMR system. Impaired waters monitoring records will also be stored in Appendix F of this SWPPP. As with the quarterly sampling described in Section 3.4, monitoring must be performed on a storm event that results in an actual discharge (“measurable storm event”) that follows the preceding measurable storm event by at least 72 hours (three days). The 72-hour (3-day) storm interval does not apply if the facility is able to document that less than a 72-hour (3-day) interval is representative for local storm events during the sampling period. In the case of snowmelt, the monitoring must be performed at a time when a measurable discharge occurs.

40 CFR 136 indicates that any of the following test methods may be used to test for pH levels:

EPA Test Method 150.2 Standard Test Method 4500-H+ B-2000 ASTM Method D1293-99 (A or B) AOAC Test Method 973.41 USGS Test Method I-1586-85 or I-2587-85 Industrial Method Number 378-75WA, Hydrogen ion (pH) Automated Electrode

Method, Bran & Luebbe (Technicon) Autoanalyzer II

3.6 Annual Summary Report

Submit an Annual Report to EPA by January 30th for each year of permit coverage (starting Jan. 30, 2017) containing information generated from the past calendar year, using EPA’s electronic NPDES eReporting tool (NeT). Include the following information:

A summary of the past year’s monthly facility inspection documentation; A summary of the past year’s quarterly visual assessment documentation;

Indeck Energy – Alexandria, LLC SWPPP 27

For any four-sample (minimum) average benchmark monitoring exceedance, if after reviewing the selection, design, installation, and implementation of control measures and considering whether any modifications are necessary to meet the effluent limits in the permit, the facility determines that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice, the rationale for why the facility believes no further reductions are achievable;

A summary of the past year’s corrective action documentation (see Section 3.8 of this Plan). If corrective action is not yet completed at the time of submission of the annual report, the facility must describe the status of any outstanding corrective action(s). Also describe any incidents of noncompliance in the past year or currently ongoing, or if none, provide a statement that the facility is in compliance with the permit;

A signed certification statement.

3.7 Previous Sampling Data

The most recent prior sampling results under the 2008 MSGP are shown in Table 3-3, which demonstrates that the facility discharge was consistently below the Total Iron benchmark (1.0 mg/L) and the discharge pH was not significantly different than the rain water (which was tested for comparison as a best management practice); therefore the 2008 MSGP did not indicate a condition of pollution at the facility. Furthermore, the wood ash analysis presented in Appendix C indicates that the wood fuel stored and used at the facility does not contain pollutants in any significant levels and should have essentially the same characteristics as the wooded environment.

3.8 Corrective Actions

Corrective action requirements are provided in Part 4 of the 2015 MSGP and are summarized below. Any corrective action-related documentation will be stored in Appendix J of this SWPPP. Blank forms to document general corrective actions, corrective maintenance activities and benchmark monitoring exceedances are also provided in Appendix J.

Indeck Energy – Alexandria, LLC SWPPP 28

3.8.1 SWPPP Review and Revision Requirements

When any of the following conditions occur or are detected during an inspection, monitoring or other means, or EPA informs the facility that any of the following conditions have occurred, this SWPPP will be reviewed and revised, as appropriate, (e.g., sources of pollution; spill and leak procedures; non-stormwater discharges; the selection, design, installation and implementation of control measures) so that the effluent limits are met and pollutant discharges are minimized:

An unauthorized release or discharge (e.g., spill, leak, or discharge of non-stormwater not authorized by this permit to a water of the U.S.) occurs at the facility.

The facility’s control measures are not stringent enough for the discharge to meet applicable water quality standards or the non-numeric effluent limits in the MSGP.

A required control measure was never installed, was installed incorrectly, or not in accordance with the MSGP, or is not being properly operated or maintained.

Whenever a visual assessment shows evidence of stormwater pollution (e.g., color, odor, floating solids, settled solids, suspended solids, foam).

Construction or a change in design, operation, or maintenance at the facility that significantly changes the nature of pollutants discharged in stormwater from the facility, or significantly increases the quantity of pollutants discharged.

The average of four quarterly sampling results (see Section 3.4) exceeds an applicable benchmark. If less than four benchmark samples have been taken, but the results are such that an exceedance of the four quarter average is mathematically certain (i.e., if the sum of quarterly sample results to date is more than four times the benchmark level) this is considered a benchmark exceedance, triggering this review.

Note: A benchmark exceedance does not trigger a corrective action if the facility determines that the exceedance is solely attributable to natural background sources, or makes a finding that no further pollutant reductions are technologically available and economically practicable and achievable in light of best industry practice (see Section 3.4).

When run-on to the facility causes a benchmark exceedance, in addition to reviewing and revising, as appropriate, the SWPPP, the facility should notify the other operators contributing run-on to the facility’s discharges to abate their pollutant contribution. Where the other operators fail to take action to address the stormwater run-on, the EPA Regional Office should be contacted.

3.8.2 Corrective Actions and Deadlines

Immediate Actions

Indeck Energy – Alexandria, LLC SWPPP 29

If corrective action is needed, the facility must immediately take all reasonable steps necessary to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational, including cleaning up any contaminated surfaces so that the material will not discharge in subsequent storm events.

Note: In this context, the term “immediately” requires the facility to, on the same day a condition requiring corrective action is found, take all reasonable steps to minimize or prevent the discharge of pollutants until a permanent solution is installed and made operational. However, if a problem is identified at a time in the work day when it is too late to initiate corrective action, the initiation of corrective action must begin no later than the following work day. “All reasonable steps” means that the facility has undertaken initial actions to assess and address the condition causing the corrective action, including, for example, cleaning up any exposed materials that may be discharged in a storm event (e.g., through sweeping, vacuuming) or making arrangements (i.e., scheduling) for a new BMP to be installed at a later date. If it is concluded that a corrective action is, in fact, not necessary, this will be documented in the SWPPP.

Subsequent Actions If the facility determines that additional actions are necessary beyond the Immediate Actions above, the facility must complete the corrective actions (e.g., install a new or modified control and make it operational, complete the repair) before the next storm event if possible, and within 14 calendar days from the time of discovery of the corrective action condition. If it is infeasible to complete the corrective action within 14 calendar days, the facility must document why it is infeasible to complete the corrective action within the 14-day timeframe. The facility must also identify the schedule for completing the work, which must be done as soon as practicable after the 14-day timeframe but no longer than 45 days after discovery. If the completion of corrective action will exceed the 45 day timeframe, the facility may take the minimum additional time necessary to complete the corrective action, provided that the facility notifies the EPA Regional Office of the intention to exceed 45 days, the rationale for an extension, and a completion date, which must also be included in the corrective action documentation. Where corrective actions result in changes to any of the controls or procedures documented in the SWPPP, the SWPPP must be modified accordingly within 14 calendar days of completing corrective action work.

Corrective Action Documentation The facility must document the existence of any of the Immediate or Subsequent conditions listed above within 24 hours of becoming aware of such condition. The facility is not required to submit the corrective action documentation to EPA, unless specifically requested to do so. However, the findings must be summarized in the annual report to EPA (section 3.6 of this Plan). The following information must be included in the documentation:

Indeck Energy – Alexandria, LLC SWPPP 30

Description of the condition triggering the need for corrective action review. For any spills or leaks, include the following information: a description of the incident including material, date/time, amount, location, and reason for spill, and any leaks, spills or other releases that resulted in discharges of pollutants to waters of U.S., through stormwater or otherwise;

Date the condition was identified; Description of immediate actions taken (see above) to minimize or prevent the

discharge of pollutants. For any spills or leaks, include response actions, the date/time clean-up completed, notifications made, and staff involved. Also include any measures taken to prevent the reoccurrence of such releases

A statement, signed and certified in accordance with Appendix B, Subsection 11 of the MSGP.

The facility must also document the corrective actions taken or to be taken as a result of the conditions requiring SWPPP review and revision (see Section 3.8.1 of this Plan) (or, for triggering events where it is determined that corrective action is not necessary, the basis for this determination) within 14 days from the time of discovery of any of those conditions. The facility must provide the dates when each corrective action was initiated and completed (or is expected to be completed). If applicable, document why it is infeasible to complete the necessary installations or repairs within the 14-day timeframe and document the schedule for installing the controls and making them operational as soon as practicable after the 14-day timeframe. If the facility notified EPA regarding an extension of the 45 day timeframe, the facility must document the rationale for an extension.

SECTION II. ACTION AREA Ensure that your action area is described in Attachment 1, as required in Step 2.

SECTION III. LISTED SPECIES AND CRITICAL HABITAT LIST Note: For the purposes of this permit, “terrestrial species” would not include animal or plant species that 1) spends any portion of its life cycle in a waterbody or wetland, or 2) if an animal, depends on prey or habitat that occurs in a waterbody or wetland. For example, shorebirds, wading birds, amphibians, and certain reptiles would not be considered terrestrial species under this definition. Please also be aware that some terrestrial animals (e.g., certain insects, amphibians) may have an aquatic egg or larval/juvenile phase.

Ensure that the listed species and critical habitat list is included in Attachment 2, as required in Step 3.

Review your species list in Attachment 2, choose one of the following three statements, and follow the corresponding instructions:

The species list includes only terrestrial species and/or their designated critical habitat. No aquatic or aquatic-dependent species or their critical habitat are present in the action area. You may skip to Section IV of this form. You are not required to fill out Section V.

The species list includes only aquatic and/or aquatic-dependent species and/or their designated critical habitat. No terrestrial species or their critical habitat are present in the action area. You may skip to Section V of this form and are not required to fill out Section IV.

The species list includes both terrestrial and aquatic or aquatic-dependent species and/or their designated critical habitat. You must fill out both Sections IV and V of this form.

SECTION IV. EVALUATION OF DISCHARGE-RELATED ACTIVITIES EFFECTS Note: You are only required to fill out this section if your facility’s action area contains terrestrial species and/or their designated critical habitat. If your action area only contains aquatic and/or aquatic-dependent species and/or their designated critical habitat, you can skip directly to Section V.

Most of the potential effects related to coverage under the MSGP are assumed to occur to aquatic and/or aquatic-dependent species. However, in some cases, potential effects to terrestrial species and/or their critical habitat should be considered as well from any discharge-related activities that occur during coverage under the MSGP. Examples of discharge-related activities that could have potential effects on listed terrestrial species or their critical habitat include the storage of materials and land disturbances associated with stormwater management-related activities (e.g., the installation or placement of stormwater control measures).

A. Select the applicable statement(s) below and follow the corresponding instructions:

There are no discharge-related activities that are planned to occur during my coverage under the MSGP. You can conclude that your discharge-related activities will have no likely adverse effects, and:

- If there are any aquatic or aquatic-dependent species and/or their critical habitat in your action area, you must skip to Section V, Evaluation of Discharge Effects, below.

- If there are no aquatic or aquatic-dependent species you may skip to Section VI and verify that your activities will have no likely adverse effects. You must submit this form to EPA as specified in Section VII of this form. You may select criterion C on your NOI form and may submit your NOI for permit coverage 30 days after you have submitted this Criterion C Eligibility Form. You must also provide a description of the basis for the criterion you selected on your NOI form, including the species and critical habitat list(s) in your action area, as well as any other documentation supporting your eligibility. You must also include this completed Criterion C Eligiblity Form in your SWPPP.

Criterion C Eligibility Form Page 3 of 11

There are discharge-related activities planned as part of the proposal. Describe your discharge-

related activities in the following box and continue to (b) below.

Describe discharge-related activities:

B. In order to ensure any discharge-related activities will have no likely adverse effects on listed species and/or their designated critical habitat, you must certify that all the following are true:

Discharge-related activities will occur: • on previously cleared/developed areas of the site where maintenance and operation of

the facility are currently occurring or where existing conditions of the area(s) in which the discharge-related activities will occur precludes its use by listed species (e.g., work on existing impervious surfaces, work occurring inside buildings, area is not used by species), and

• if discharge-related activities will include the establishment of structures (including, but not limited to, infiltration ponds and other controls) or any related disturbances, these structures and/or disturbances will be sited in areas that will not result in isolation or degradation of nesting, breeding, or foraging habitat or other habitat functions for listed animal species (or their designated critical habitat), and will avoid the destruction of native vegetation (including listed plant species).

If vegetation removal (e.g., brush clearing) or other similar activities will occur, no terrestrial listed species that use these areas for habitat would be expected to be present during vegetation removal.

If all the above are true, you can conclude that your discharge-related activities will have no likely adverse effects, and:

- If there are any aquatic or aquatic-dependent species and/or critical habitat in your action area, you must skip to Section V, Evaluation of Discharge Effects, below.

- If there are no aquatic or aquatic-dependent species you may skip to Section VI and verify that your activities will have no likely adverse effects. You must submit this form to EPA as specified in Section VII of this form. You may select criterion C on your NOI and may submit your NOI for permit coverage 30 days after you have submitted this completed form. You must also provide a description of the basis for the criterion you selected on your NOI form, including the species and critical habitat list(s), and any other documentation supporting your eligibility. You must also include this completed Criterion C Eligibility Form in your SWPPP.

- If any of the above are not true, you cannot conclude that your discharge-related activities will have no likely adverse effects. You must complete the rest of this form (if applicable), and must submit the form to EPA for assistance in determining your eligibility for coverage.

Criterion C Eligibility Form Page 4 of 11

SECTION V. EVALUATION OF DISCHARGE EFFECTS Note: You are only required to fill out this section if your facility’s action area includes aquatic and/or aquatic-dependent species and/or their critical habitat.

In this section, you will evaluate the likelihood of adverse effects from your facility’s discharges. The scope of effects to consider will vary with each facility and species/critical habitat characteristics. The following are examples of discharge effects you should consider:

• Hydrological Effects. Stormwater discharges may adversely affect receiving waters from pollutant parameters such as turbidity, temperature, salinity, or pH. These effects will vary with the amount of stormwater discharged and the volume and condition of the receiving water. Where a stormwater discharge constitutes a minute portion of the total volume of the receiving water, adverse hydrological effects are less likely.

• Toxicity of Pollutants. Pollutants in stormwater may have toxic effects on listed species and may adversely affect critical habitat. Exceedances of benchmarks, effluent limitation guidelines, or state or tribal water quality requirements may be indicative of potential adverse effects on listed species or critical habitat. However, some listed species may be adversely affected at pollutant concentrations below benchmarks, effluent limitation guidelines, and state or tribal water quality standards. In addition, stormwater pollutants identified in Part 5.2.3.2 of your SWPPP, but not monitored as benchmarks or effluent limitation guidelines, may also adversely affect listed species and critical habitat.

As these effects are difficult to analyze for listed species, their prey, habitat, and designated critical habitat, this form helps you to analyze your discharges and make a determination of whether your discharges will have likely adverse effects and whether there are any additional controls you can implement to ensure no likely adverse effects.

A. Evaluation of Pollutants and Controls to Avoid Adverse Effects. In this section, you must document all of your pollutant sources and pollutants expected to be discharged in stormwater. You must also document the controls you will implement to avoid adverse effects on listed aquatic and aquatic-dependent species. You must include specific details about the expected effectiveness of the controls in avoiding adverse effects to the listed aquatic-and aquatic-dependent species. Attach additional pages if needed.

Potential Pollutant Source Potential Pollutants

Controls to Avoid Adverse Effects on Listed Aquatic and Aquatic-Dependent Species. Include information supporting why the control(s) will ensure no adverse effects, including any data you have about the effectiveness of the control(s) in reducing pollutant concentrations. You may also attach photos of your controls to this form.

e.g., vehicle and equipment fueling

e.g., • Oil & grease • Diesel • Gasoline • TSS • Antifreeze

e.g., • Fueling operators (including the transfer of fuel from

tank trucks) will be conducted on an impervious or contained pad or under cover

• Drip pans will be used where leaks or spills of fuel can occur and where making and breaking hose connections

• Spill kit will be kept on-site in close proximity to potential spill areas

• Any spills will be cleaned-up immediately using dry clean up methods

• Stormwater runoff will be diverted around fueling areas using diversion dikes and curbing

Potential Pollutant Source Potential Pollutants Controls to Avoid Adverse Effects on Listed Aquatic and Aquatic-Dependent Species.

Check if you are not able to make a preliminary determination that any of your pollutants will be controlled to a level necessary to avoid adverse effects on aquatic and/or aquatic-dependent listed species and their designated critical habitat. You must check in Section VI that you are unable to make a determination of no likely adverse effects, and must complete the rest of the form. You must submit your completed form to EPA for assistance in determining your eligibility for coverage.

Criterion C Eligibility Form Page 7 of 11

B. Analysis of Effects Based on Past Monitoring Data. Select which of the following applies to your facility:

I have no previous monitoring data for my facility because there are no applicable monitoring requirements for my facility’s sector(s).

I have no previous monitoring data for my facility because I am a new discharger or a new source, but I am subject to monitoring under the 2015 MSGP. You must provide information to support a conclusion that your facility’s discharges are not expected to result in benchmark or numeric effluent limit exceedances that will adversely affect listed species or their critical habitat:

My facility has not had any exceedances under the 2008 MSGP of any required benchmark(s) or numeric effluent limits.

My facility has had exceedances of one or more benchmark(s) or numeric effluent limits under the 2008 MSGP, but I have addressed them during my coverage under the 2008 MSGP, or in my evaluation of controls to avoid adverse effects in (A) above. Describe all actions (including specific controls) that you will implement to ensure that the pollutants in your discharge(s) will not result in likely adverse effects from future exceedances.

Check if your facility has had exceedances of one or more benchmarks or numeric effluent limits under the 2008 MSGP and you have not been able to address them to avoid adverse effects from future exceedances, or if you are a new discharger or a new source but you are not sure if you can avoid adverse effects from possible exceedances. You must check in Section VI that you are unable to make a determination of no likely adverse effects. You must submit your completed form to EPA for assistance in determining your eligibility for coverage. You may not file your NOI for permit coverage until you are able to make a determination that your discharges will avoid adverse effects on listed species and designated critical habitat.

SECTION VI VERIFICATION OF PRELIMINARY EFFECTS DETERMINATION Based on Steps I – V of this form, you must verify your preliminary determination of effects on listed species and designated critical habitat from your discharges and/or discharge-related activities :

Following the applicable Steps in I – V above, I have made a preliminary determination that my discharges and/or discharge-related activities are not likely to adversely affect listed species and designated critical habitats.

Following the applicable Steps in I – V above, I am not able to make a preliminary determination that my discharges and/or discharge-related activities are not likely to adversely affect listed species and designated critical habitats.

Certification Information I certify under penalty of law that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gathered and evaluated the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the information submitted is, to the best of my knowledge and belief, true, accurate, and complete.

Criterion C Eligibility Form Page 8 of 11

Attachment 1 Include a map and a written description of the action area of your facility, as required in Step 2. You may choose to include the map that is generated from the FWS’ on-line mapping tool IPaC (the Information, Planning, and Consultation System) located at http://ecos.fws.gov/ipac/.

The written description of your action area that accompanies your action area map must explain your rationale for the extant of the action area drawn on your map. For example, your action area written description may look something like this:

The action area for the (name of your facility)’s stormwater discharges extends downstream from the outfall(s) in (name of receiving waterbody) (# of meters/feet/kilometers/miles). The downstream limit of the action area reflects the approximate distance at which the discharge waters and any pollutants would be expected to cause potential adverse effects to listed species and/or critical habitat because (insert rationale). The action area does/does not extend to the (name of receiving waterbody)’s confluence with (name of confluence waterbody) because (insert rationale).

Note that you action area written description will be highly site-specific, depending on the expected effects of your facility’s dishcarges and discharge-related activities, receiving waterbody characteristics, etc.

Attachment 2 List or attach the listed species and critical habitat in your action area on this sheet, as required in Step 3. You must include a list for applicable listed NMFS and FWS species and critical habitat. If there are listed species and/or critical habitat for only one Service, you must include a statement confirming there are no listed species and/or critical habitat for the other Service. For FWS species, include the full printout from your IPaC query. Note: If your Official Species List from the USFWS indicated no species or critical habitat were present in your action area, include the full consultation tracking code at the top of your Official Species List in your NOI submittal in the question “Provide a brief summary of the basis for the criterion selected in Appendix E.” If an Official Species List was not available on IPaC, list the contact date and name of the Service staff with whom you corresponded to identify the existence of any USFWS species or critical habitat present in your action area.

Subject: List of threatened and endangered species that may occur in your proposed projectlocation, and/or may be affected by your proposed project

To Whom It May Concern:

The enclosed species list identifies threatened, endangered, proposed and candidate species, aswell as proposed and final designated critical habitat, that may occur within the boundary ofyour proposed project and/or may be affected by your proposed project. The species list fulfillsthe requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of theEndangered Species Act (Act) of 1973, as amended (16 U.S.C. 1531 ).et seq.

New information based on updated surveys, changes in the abundance and distribution ofspecies, changed habitat conditions, or other factors could change this list. Please feel free tocontact us if you need more current information or assistance regarding the potential impacts tofederally proposed, listed, and candidate species and federally designated and proposed criticalhabitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 ofthe Act, the accuracy of this species list should be verified after 90 days. This verification canbe completed formally or informally as desired. The Service recommends that verification becompleted by visiting the ECOS-IPaC website at regular intervals during project planning andimplementation for updates to species lists and information. An updated list may be requestedthrough the ECOS-IPaC system by completing the same process used to receive the enclosedlist.

The purpose of the Act is to provide a means whereby threatened and endangered species andthe ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2)of the Act and its implementing regulations (50 CFR 402 ), Federal agencies are requiredet seq.to utilize their authorities to carry out programs for the conservation of threatened andendangered species and to determine whether projects may affect threatened and endangeredspecies and/or designated critical habitat.

A Biological Assessment is required for construction projects (or other undertakings havingsimilar physical impacts) that are major Federal actions significantly affecting the quality of thehuman environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)(c)). For projects other than major construction activities, the Service suggests that a biologicalevaluation similar to a Biological Assessment be prepared to determine whether the project mayaffect listed or proposed species and/or designated or proposed critical habitat. Recommendedcontents of a Biological Assessment are described at 50 CFR 402.12.

If a Federal agency determines, based on the Biological Assessment or biological evaluation,that listed species and/or designated critical habitat may be affected by the proposed project, theagency is required to consult with the Service pursuant to 50 CFR 402. In addition, the Servicerecommends that candidate species, proposed species and proposed critical habitat be addressedwithin the consultation. More information on the regulations and procedures for section 7consultation, including the role of permit or license applicants, can be found in the "EndangeredSpecies Consultation Handbook" at:

http://www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF

Please be aware that bald and golden eagles are protected under the Bald and Golden EagleProtection Act (16 U.S.C. 668 ), and projects affecting these species may requireet seq.development of an eagle conservation plan(http://www.fws.gov/windenergy/eagle_guidance.html). Additionally, wind energy projectsshould follow the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizingimpacts to migratory birds and bats.

Guidance for minimizing impacts to migratory birds for projects including communicationstowers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at:http://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;http://www.towerkill.com; andhttp://www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/comtow.html.

We appreciate your concern for threatened and endangered species. The Service encouragesFederal agencies to include conservation of threatened and endangered species into their projectplanning to further the purposes of the Act. Please include the Consultation Tracking Number inthe header of this letter with any request for consultation or correspondence about your projectthat you submit to our office.
