Advanced Notice of Proposed SPDES Permit for Discharges of Winery, Brewery and Hard Cidery Wastewater to Groundwater
Through this Advanced Notice of Proposed Permit (ANPP) (PDF, 252KB), the Department is soliciting stakeholder input regarding the potential issue of a State Pollution Discharge Elimination System (SPDES) general permit that would provide coverage for wastewater discharges to groundwater from licensed wineries, breweries, and hard cideries in New York State through this industry survey known as an ANPP. The Department is specifically seeking input on questions listed at the end of the ANPP. Additional information that may be relevant to the ANPP may also be provided to the Department.
DEC will accept comments on the ANPP from April 1, 2018 until May 31, 2018. Comments must be submitted in writing by mail or email to:

Draft SPDES General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (GP-0-17-002)
The Department has prepared a DRAFT renewal of the State Pollutant Discharge Elimination System (SPDES) General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (GP-0-17-002) (PDF, 2.8 MB). When final, GP-0-17-002 will replace the current MS4 General Permit, GP-0-15-003, which is due to expire on April 30, 2017. GP-0-17-002 will be effective for a five (5) year term and will cover discharges of stormwater to surface waters of the State from small MS4s as defined in 40 CFR Part 122.26(a)(1)(v), 122.26(b)(8), and 122.26(b)(16)-(19).
The Department is also making two versions of the recently updated "Sample Local Law for Stormwater Management and Erosion & Sediment Control" (draft dated October 21, 2016) and the "Draft Greenwood Lake Watershed Phosphorus TMDL Implementation Plan" available for public review and comment. Both documents are referenced in the draft renewal of the MS4 General Permit.
- Sample Local Law for Stormwater Management and Erosion & Sediment Control - NYSDEC worked with the NYS Department of State through the Community Risk & Resiliency Act (CRRA) Model Law effort to prepare the "Draft Sample Local Law for Stormwater Management and Erosion and Sediment Control, October 21, 2016." This sample law provides updates to reflect the current requirements of the Construction General Permit and proposed draft MS4 renewal. There are two versions of the Draft Sample Local Law. When finalized, the MS4 renewal will require MS4 Operators to adopt the basic version that includes, among other changes, green infrastructure practices as required in the New York State Stormwater Management Design Manual. Although not required, MS4 Operators are encouraged to consider the second version which provides additional resiliency provisions that allow communities to require a more detailed green infrastructure site planning process and consider riparian buffers and other sensitive natural resources.
- Draft Greenwood Lake Watershed Phosphorus TMDL Implementation Plan - The Department has drafted the "Greenwood Lake Watershed Phosphorus TMDL Implementation Plan ". The Draft Implementation plan includes strategies to reduce the regulated sources of phosphorus in New York State and to reduce unregulated sources through voluntary action on the part of Greenwood Lake watershed stakeholders. The Town of Warwick, Village of Greenwood Lake, NYSDOT and Orange County are all stakeholders and regulated MS4 Operators, and are specifically identified as requiring phosphorus reductions in this watershed.

Maintenance Guidance for Stormwater Management Practices
The Department has developed Maintenance Guidance for Stormwater Management Practices (draft) (PDF, 4.8 MB). The purpose of this document is to provide guidance on how to inspect and maintain the stormwater management practices found in the New York State Stormwater Design Manual. Guidance is provided for all levels of skill including homeowners; low to moderately skilled municipal staff; highly trained municipal employees; and design professionals such as professional engineers, landscape architects or other professionals who can revisit design issues associated with chronic or serious maintenance problems.

Long Island MS4 Implementation Plan for Pathogen Impaired Waters
The Department has drafted the "Implementation Plan for Pathogen Impaired Waters in Part IX.C of the SPDES General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (MS4s)" (PDF, 132 KB) to provide guidance to MS4 Operators located within pathogen impaired watersheds on Long Island where EPA-approved TMDLs require pathogen reductions from MS4 discharges to meet water quality standards. This draft guidance document presents information received from Long Island MS4 Operators on the extent and land use within their MS4 sewersheds that discharge to the 70 pathogen impaired waters listed in Part IX.C of the MS4 General Permit. The draft guidance also explains the methodology used to model the predicted individual MS4 pathogen load contribution(s); identifies the appropriate pollutant load reductions required of MS4s above the TMDL allowable pollutant load; and identifies further actions necessary to achieve the applicable pollutant load reductions through the MS4 General Permit renewal. As a companion to the draft LI MS4 Implementation Plan, the Department has also developed the Pathogen Reduction Credit Worksheet (XLSX, 106 KB), an Excel-based spreadsheet that will allow MS4 Operators to calculate reduction credits associated with existing stormwater management practices and future retrofits.
