TxDOT CORRESPONDENCE

June 19, 2020 Chad Windham, P.E. Director of Operations Texas Department of Transportation 3901 E Highway 80 Odessa, TX 79761 RE: Diamond Back Solid Waste Facility & Recycling Center

Permit Application Dear Mr. Windham,

In response to the letter dated June 10, 2020, Parkhill, Smith & Cooper (PSC) offers the following to address your comments. PSC proposes a new driveway for the facility. The proposed driveway will be constructed to meet the current Access Management Standards of TxDOT and uses guidance from the Odessa District IAC Technical Memorandum concerning access management. The new driveway will be constructed of concrete and will include a 34-ft wide throat and 60-ft radii. A traversable apron with 70-ft radii will be constructed of caliche base. This design will allow trucks to enter the drive even while a vehicle is waiting to exit, without having to slow excessively on FM 866. Additionally, the shoulder will be widened 10 feet from the white edge line 250 feet either side of the driveway. This will allow traffic to use the shoulder to either slow as it approaches the drive or accelerate as it exits the drive with less impact on FM 866 through traffic. The proposed plan view of the driveway can be seen in Attachment 1. An application for a new driveway permit will be submitted upon issuance of the municipal solid waste permit. The driveway permit will be submitted prior to, but within 6 months of driveway construction. An updated traffic analysis will be available upon a formal request from TxDOT after facility is fully operational. Updates to the driveway for additional turn lanes or similar features shall be constructed if evaluation indicates sufficient disparity. We request TxDOT concur with our recommendation. If you need any further information, please do not hesitate to contact me at 469.200.7363.

Sincerely,

PARKHILL, SMITH & COOPER, INC.

June 10, 2020 Mr. Todd Stiggins Parkhill Smith & Cooper (PSC) 4222 85th Street Lubbock, Texas 79423 RE: Diamond Back Solid Waste Facility & Recycling Center Dear Mr. Stiggins, TxDOT Odessa District has reviewed the traffic analysis that was performed for the above-mentioned site located on FM 866 approximately 2 miles north of IH 20 in Ector County and we offer the following comments.

• TxDOT has concerns about the traffic modeling methodology and projections utilized in the analysis and their applicability to the site conditions. However, we understand the difficulty in obtaining accurate traffic projections utilizing currently available information and standard procedures.

• Because the modeling should use nonstandard procedures, , TxDOT may request a re-evaluation of the traffic analysis and projections against actual traffic volumes and patterns once the site is made fully operational. We reserve the right to require additional turn lanes or similar features if the comparative evaluation indicates sufficient disparity.

• What are the details and location of the new driveway into the facility? This will require application for and issuance of a new driveway permit. TxDOT will need to evaluate and determine if the driveway can be accommodated with the additional development that has occurred near this site.

• Speed reductions would require an engineering study and would need to look at the entire FM 866 corridor. Speed reductions for a specific access or development are not usually recommended.

• The existing driveway was approved in 2017 and was submitted as a temporary or Phase 1 access based on 1 or 2 vehicles per hour. The driveway permit called for a 30’ throat width with 75’ radii, but the current driveway was not constructed in accordance with this permit. It must be reconstructed to meet current Access Management Standards. We do not recommend placement of 2 exit lanes as these movements will conflict with each other, increase conflict points, and potentially cause safety concerns.

• As the traffic analysis shows there is added safety value in the inclusion of turn bays on FM 866, but as discussed above, additional and accurate traffic data will be needed. The driveway should be designed to accommodate the turning movements for the anticipated vehicle usage along with a shoulder widening 250’ each side of the driveway to obtain a minimum 10’ shoulder. The shoulder widening is required to mitigate the edge drop-off issues that are typically seen with truck traffic entering and exiting the facility. Attached is our current standards for commercial and industrial driveways.

Water Balance Final Cover construction shall be subjected to an approval of a permit

modification from TCEQ to include complete design of the final cover. Pre-construction testing

will be conducted on the borrow soil material. Thickness of Water Balance Final Cover will be

determined from hydraulic conductivity of the borrow soil. Tests will be conducted during

construction, to verify that final cover geometric mean hydraulic conductivity is not greater than

the borrow soil test results.

As provided for in TCEQ RG-494, no vegetation is required for the water balance final cover to

function as designed. Vegetation will be established within the erosion layer to provide for

additional protection from erosion. Native grasses will be established immediately following

construction of the water balance final cover. Refer to Appendix III.H.2 - Final Cover Quality

Control Plan for construction requirements.

The final cover system will be maintained consistent with Part III, Attachment I – Post-Closure

Plan. Following facility closure, final cover will be maintained as described in Attachment I -

Post-Closure Plan. Final cover soil layer will be constructed in accordance with construction

details shown in Part III, Appendix III.H3 –Final Cover Figures and Details, Figure III.H2.

Testing 5 feet of compacted clay-rich cover soil for coefficient of permeability will occur no less

than one test per acre of final cover.

Revised Universal Soil Loss Equation (RUSLE) calculations predict rate of soil loss for final

cover to be within TCEQ guidelines. RUSLE calculations are included in Appendix III.C.3.

2.0 FINAL COVER SYSTEM

2.1 FINAL COVER

2.1.1 Prescriptive Final Cover

The prescriptive final cover system will consist of an infiltration layer, a flexible

geomembrane, drainage geocomposite and erosion control layer on top. The infiltration

layer will 18 inches of compacted soil with a coefficient of permeability less than or equal

to 1x10-5 cm/sec. The flexible geomembrane will be a 40 mil LLLDPE geomembrane

placed over the infiltration layer. The drainage layer will be double sided geocomposite

and the erosion layer will be 6 inches of soil. Erosion layer will be placed over the drainage

layer and be capable of sustaining native plant growth. The final cover will be seeded with

native grasses and plants immediately following soil placement to minimize erosion. Final

cover system will be maintained consistent with those defined in Part III, Attachment C -

Facility Surface Water Drainage Report.

2.1.2 Alternative/Water Balance Final Cover

In accordance with 30 TAC $330.457(d), Diamond Back Solid Waste Facility & Recycling

Center will install an alternate final cover over both Type I and Type IV disposal areas.

The alternate final cover will consist of a water balance final cover designed in accordance

with TCEQ Regulatory Guidance RG-494 Guidance for Requesting a Water Balance (WB)

Final Cover for a Municipal Solid Waste Landfill. TCEQ RG-494 is included in

Appendix III.H.1. TCEQ RG-494 provides for four options for water balance final cover.

Diamond Back Solid Waste Facility & Recycling Center will utilize Option 1 - Statewide

Design Table for construction water balance final covers at the facility.

In accordance with TCEQ RG-494, the water balance cover will consist of a minimum

18-inch-thick storage layer overlain by a minimum 6-inch thick erosion layer. The

thickness of each final cover layer may vary depending upon the hydraulic conductivity of

the borrow soil material. Water Balance Final Cover construction shall be subjected to an

approval of a permit modification from TCEQ to include a complete design of the final

cover.

As provided for in TCEQ RG-494, no vegetation is required for the water balance final

cover to function as designed. Vegetation will be established within the erosion layer to

provide for additional protection from erosion. Native grasses will be established

immediately following construction of the water balance final cover.

The Final Cover System will be constructed from onsite soil and seeded with native grasses

and plants immediately following soil placement to minimize erosion. Final cover system

will be maintained consistent with those defined in Part III, Attachment C - Facility Surface

Water Drainage Report. Following facility closure, the final cover will be maintained as

described in Part III, Attachment I – Post-Closure Plan.




The final cover system will be constructed in accordance with construction details shown

in Appendix III.H.3 - Final Cover Figures and Details and specifications provided herein.

2.2 CONSTRUCTION MONITORING

Continuous on-site monitoring is necessary to assure components of final cover system

are constructed in accordance with this FCQCP. CQA monitor shall provide continuous

on-site observation during the following activities:

• Infiltration/Storage layer placement, processing, compaction, and testing;

• Flexible membrane layer deployment, trial welds, seaming, testing, and repairing (for

prescriptive cover only);

• Drainage layer deployment and seaming (for prescriptive cover only);

• Erosion layer placement; and

• Any work that could damage installed components of final cover system.

GP or POR will document and certify the final cover system was constructed in accordance

with this FCQCP. GP or POR shall make sufficient site visits to observe critical

construction activities and verify construction and QA activities are performed in

accordance with this FCQCP.

3.0 INTERMEDIATE COVER AND GRADING

3.1 GENERAL

Landfill completion plan provides for the landfill cover to slope to the perimeter 4H:1V

side slopes. Final lift of waste will be covered by intermediate cover placed in accordance

with the Part IV - Site Operating Plan.

3.2 MATERIALS

Intermediate cover will consist of general fill that has not previously come into contact

with waste.

3.3 SLOPES

Slope stability analyses are provided in Attachment D5 – Geotechnical Design,

Appendix D5.B, and are only valid for conditions that were analyzed. Any changes to final




cover system or landfill completion plan will necessitate slope stability analyses be revised

to reflect actual conditions. Further, slope stability analyses represent end-of-construction

conditions and may not represent temporary conditions during construction. Temporary

construction slopes shall not be steeper than final slopes and concentrated loadings, such

as heavy equipment and soil stockpiles, and not placed near the crest of slopes unless

additional slope stability analyses are performed.

3.4 TESTING AND VERIFICATION

Intermediate cover placement and grading will be observed and documented by landfill

staff in accordance with the Site Operating Plan.

4.0 INFILTRATION/STORAGE LAYER

4.1. GENERAL

The infiltration/storage layer will consist of compacted, relatively homogeneous material.

Infiltration layer shall consist of soil that is free from debris, foreign objects and organic

material. The soil properties for the infiltration layer shall meet the following: plasticity

index (ASTM D 4318) 15 or greater; liquid limit (ASTM D 4318) 30 or greater; percent

passing 200 sieve (ASTM D 1140) 30 or greater; and coefficient of permeability (ASTM

D 5084 or COE EM 1110-2-1906 Appendix VII) 1x10-5 cm/sec or less.

The minimum required thickness of the storage layer is derived from Option 1 - Statewide

Design Table of TCEQ Regulatory Guidance RG-494 Guidance for Requesting a Water

Balance (WB) Final Cover for a Municipal Solid Waste Landfill. TCEQ RG-494 is

included in Appendix III.H.1. CQA monitor shall provide continuous on-site observation

during storage layer placement, processing, compaction, and testing. GP shall make

sufficient site visits during storage layer construction to document construction activities,

testing, and thickness verification in the Final Cover FCER Report, in accordance with

Section 6.0.

Through normal operation, soils will be stored in stockpiles and borrow areas and shall be

used in preconstruction testing for use in the development of the water balance final cover.

Preconstruction testing procedures and frequencies for storage layer materials are listed in

Section 4.7.1 Table 2.




4.2 SUBGRADE PREPARATION

Before placing infiltration/storage layer material, subgrade should be proof rolled with

heavy, rubber-tired construction equipment to detect soft areas. POR or CQA monitor must

observe proof-rolling operation. Soft areas should be compacted then proof rolled again.

Subgrade elevations shall be verified in accordance with requirements of Section 4.7.3

before placing storage layer.

4.3 PLACEMENT AND PROCESSING

The infiltration layer/storage layer subgrade and surface of each lift should be scarified to

a 6-inch minimum depth before placing next lift of storage layer. Storage layer material

should be placed in 8-inch maximum loose lifts to produce a compacted lift thickness of

approximately 6 inches. Material should be processed to a maximum particle size of 1 inch

or less before water is added. Rocks and clods less than 1 inch in diameter should not total

more than about 10 percent by weight. Surface of top lift shall contain no material larger

than 3/8 inch.

If additional water is necessary to adjust moisture content, apply after initial processing but

before compaction. Water should be applied evenly across the lift and worked in the

material. Waste or any objectionable material must not contaminate compaction water.

In accordance with TCEQ RG-494, the minimum thickness of the storage layer is 18

inches. The required thickness of the storage layer shall be determined before constructing

the final cover. During preconstruction, on-site soils from stockpiles or borrow areas will

be assessed for hydraulic conductivity to thickness values in Table 1. To maintain

permitted final cover grades, the final top of waste heights will be adjusted based on storage

layer thickness requirements. Table 1 is excerpted from Table 3 in Section 10 of TCEQ

RG-494, which shows the relationship of hydraulic conductivity to storage layer thickness.

Table 1 - MINIMUM STORAGE LAYER THICKNESS

KAS-BUILT (cm/sec) Minimum Storage Layer Thickness (ft-in)

1.00E-08 1 ft 0 in*

5.00E-08 1 ft 3 in*

1.00E-07 1 ft 7 in

4.50E-07 1 ft 10 in

5.40E-05 6 ft 2 in

*Although Table 3 of Section 10 of TCEQ RG-494 allows for minimum storage layer thickness less than 18 inches, minimum storage layer thickness shall be at least 18 inches in accordance with Table 2 of Section 9 of TCEQ RG-494.




4.4 COMPACTION

Infiltration/Storage layer shall be compacted with a pad/tamping-foot or prong-foot roller.

A footed roller is necessary to bond lifts, distribute water, and blend soil matrix through

kneading action. Storage layer shall not be compacted with bulldozer, rubber-tired or flat-

wheeled roller, scrapers, or any track equipment unless used to pull a footed roller.

Compactor should weight at least 40,000 pounds. Lift thickness shall be controlled to

achieve total penetration in the top of the previously-compacted lift; therefore, lift thickness

must not be greater than pad or prong length. Cleaning devices on the roller must be in

place and maintained to prevent prongs or pad feet from becoming clogged to the point

they cannot achieve full penetration.

Compactor shall make at least four passes across area being compacted. A pass is defined

as the front and rear drums of the compactor making one pass. Material should be

compacted to a minimum 95-percent of the maximum dry density determined by Standard

Proctor (ASTM D698) at a moisture content dry of optimum moisture. Areas with failing

tests shall be reworked, recompacted, then retested with passing tests before another lift is

added.

4.5 PROTECTION

Completed infiltration/storage layer must be protected from desiccation, rutting, erosion,

and ponded water until erosion layer is placed. Areas that undergo excessive desiccation

or damage shall be reworked, recompacted, and retested as directed by GP or POR.

4.6 TIE IN TO EXISTING COVERS

Edge of existing storage layers shall be cut back on either a slope or step to prevent

formation of a vertical joint.

Field moisture contents of constructed soil cover should be in the dry of optimum

region.

After the moisture density relationship is determined for a material type, a soil

sample should be remolded to about 95-percent maximum dry density at the

optimum moisture content. The preconstruction testing of borrow soils will be used

to determine hydraulic conductivity and minimum storage layer thickness of final

cover by using Table 1, in accordance with TCEQ Regulatory Guidance RG-494

Guidance for Requesting a Water Balance Final Cover for a Municipal Solid Waste

Landfill.

Undisturbed constructed soil cover samples should be collected in 3-inch or greater

diameter thin-wall tubes at a frequency of at least one test per 2.5 acres per lift and

tested in the laboratory for moisture content, dry unit weight, and saturated

hydraulic conductivity. Water balance construction methods must ensure as-built

soil density is adequate for sufficient vegetation growth, maintaining design values

for unsaturated hydraulic conductivity, and minimizing developments of cracks,

macro features, and differential settlement.




4.7.2 Construction Testing

Table 3 lists minimum testing required for material used for use as the storage layer:

Atterberg limits of in-place infiltration/storage layer must be continually compared

to Atterberg limits of the Proctor curve sample to assure Proctor curve accurately

represents in-place material. Any variance of more than 10 points between liquid

limit or plasticity index of in-place soil and those of the Proctor curve sample, will

require a new Proctor curve be developed.

4.7.3 Thickness Verification

As-built thickness of infiltration/storage layer shall be determined by standard

survey methods. Before placing infiltration/storage layer material, subgrade

elevations will be determined at a minimum rate of one survey point per 5,000

square feet of lined area. After infiltration/storage layer is completed, top of

infiltration/storage layer elevations will be determined at same locations as

subgrade elevations.

During construction, storage layer soil samples will be assessed for as-built

hydraulic conductivity to verify minimum storage thickness determined from

preconstruction. Areas with hydraulic conductivity higher than determined during

preconstruction will be further compacted and retested. The thickness of the storage

layer may be adjusted based on the results of construction testing of hydraulic

conductivity and comparison to Table 1, in accordance with TCEQ Regulatory

Guidance RG-494 Guidance for Requesting a Water Balance Final Cover for a

Municipal Solid Waste Landfill. To maintain permitted final cover grades, the final

top of waste heights will be adjusted based on storage layer thickness requirements.
