What is a Combined Sewer Overflow?

NYC’s sewer system is approximately 60% combined, which means it

is used to convey both sanitary and storm flows.

When the sewer system is at full capacity, a diluted mixture of rain water and

sewage may be released into local waterways. This is called a combined sewer

overflow (CSO).

65% to 90% of combined sanitary & storm flow is captured at treatment plants.

What is a LTCP and CSO Consent Order?

Long Term Control Plan (LTCP)

identifies appropriate CSO controls to achieve applicable

water quality standards

consistent with the Federal CSO Policy and Clean Water Act

CSO Consent Order

an agreement that settles past legal disputes without

prolonged litigation

requires DEP to develop LTCPs and mitigate CSOs

Flushing Creek Drainage Area

Flushing Creek is located in north-

central Queens and discharges into

Flushing Bay

Over 500 acres of the watershed

tributary drain to fresh water Meadow

and Willow Lakes

Flushing Creek is classified by New

York State DEC for secondary contact

recreation

Class I – Boating and Fishing

DEP wet-weather discharges include:

3 CSO Outfalls

5 Stormwater Outfalls

Green Infrastructure in New York City

Green Infrastructure (GI) collects

stormwater runoff from impervious

surfaces, such as streets and roofs,

reducing flow to sewers

2012 Consent Order requires GI

investments over 20 years

$1.5 billion budgeted for GI Citywide to

manage 1” of stormwater runoff from

10% of impervious combined sewered

areas by 2030

DEP will meet this goal through:

• Area-Wide Contracts

• Public Property Retrofits

• Grant Program for Private Property Owners

• Stringent Detention Rule for New Development

Permeable Pavers

Green Roofs

Bioswales

(right of way green infrastructure)

18

GI Opportunities for Private Property Owners

Green Infrastructure Grant Program: DEP provides funding for the design and construction costs of green

infrastructure on private property in combined sewer areas of the City.

Green Roof Tax Abatement:The City provides a one-year property tax abatement for private

properties that install green roofs. The abatement value is $5.23 per

square foot (up to the lesser of $200,000 or the building’s tax liability)

and is available through March 15, 2018.

2012 Stormwater Rule:In 2012, DEP amended the allowable flow rate of stormwater to the

City’s combined sewer system for new and existing development. Site

Connection Proposals may include green infrastructure technologies

to meet the new allowable rate.

19

Planned Green Infrastructure in Flushing Creek

Area-Wide GI Contracts:

• TI-022 – Geotechnical investigations

are complete

• TI-011 – Geotechnical investigations

are underway

• TI-010 – Design will begin this

fall/winter

PS 185Q:

• Construction began September 2015

• Rain garden and synthetic turf field

for “Schoolyards to Playgrounds”

project with TPL/SCA/DOE

Flushing Town Hall:

• In construction

• Rain garden and swales with the

Department of Cultural Affairs

.

20

Flushing Creek Preferred Alternative

Recreational Season Disinfection (May 1st – Oct. 31st)

*TI-010 – Disinfect at Influent Screens and DC5

*TI-011 – Disinfect at Regulator 9

TI-010 TI-011

Benefits

• Provides disinfection of

tank bypass flows

• Minimizes footprint as

disinfection equipment

can be installed at

existing site

• Utilizes gravity, no

effluent pumping

• Maximizes use of

existing infrastructure

• Cost effective; no

retention tank needed

Challenges

• May require control

structure at end of

outfall

• Potential residual

chlorine issues

• Potential impacts due

to street work

• May require control

structure at end of

outfall

• Potential residual

chlorine issues

• May require site

acquisition

Construction $2 Million $5 Million

O&M Cost $350,000 per Year $300,000 per Year

*Note: Provisions for floatables control to be

evaluated and included in the design for both TI-010

and TI-011.

Waterbody/Watershed Facility Plan (WWFP) Recommended

Implementation of Three Grey Infrastructure Projects:

1) Divert Low-Lying Sewers / Raise Weir BB-02

2) Regulator Modifications

3) Environmental Dredging of Flushing Bay

49

1) Divert Low-Lying Sewers / Raise Weir BB-02

Divert low-lying sewers in the vicinity of Bowery Bay WWTP

and raise the weir at regulator BB-02

• Estimated Cost

= $5.6 Million

• Construction Completion

= December 2016

• Current Status

= In Construction

2) Regulator Modifications

Bowery Bay high level

interceptor regulator

modifications at 5

regulators: BB-R4, BB-R5,

BB-R6, BB-R9, and BB-R10

• Estimated Cost

= $41.4 Million

• Construction Completion

= June 2018

• Current Status

= Design Completed

Regulator modification at

BB-R2 is covered under a

3) Environmental Dredging of Flushing Bay

Removal of CSO related sediments

that are exposed at low tides

Dredge Area = 17.5 acres

Dredge Quantity = 91,600 cubic yards

Post-Dredge Depth = 4 feet below mean

lower low water

Removal of deteriorated piles and

abandoned Pier head at Pier 2

• Estimated Cost = $38.8 Million

• Current status = Design Completed
