Stormwater Management Background

New York State Stormwater Management Design Manual (August, 2015)

The New York State Stormwater Management Design Manual provides designers with a general overview on how to size, design, select, and locate stormwater management practices at a development site to comply with State stormwater performance standards. This manual is a key component of the Phase II State Pollution Discharge Elimination System (SPDES) general permit for stormwater runoff from construction activities from all sizes of disturbance.

This manual has been prepared by the Center for Watershed Protection for New York State Department of Environmental Conservation and made available to the Empire State Chapter of the Soil and Water Conservation Society for distribution.

New York State Standards and Specifications for Erosion and Sediment Control
DEC is making the draft update of the New York State Standards and Specifications for Erosion and Sediment Control available for public review and comment.

The purpose of this document is to provide minimum standards and specifications for meeting criteria set forth by NYS DEC for stormwater discharges associated with construction activity. The standards and specifications provide criteria on minimizing erosion and sediment impacts from construction activity involving soil disturbance.

The current technical standard is now ten years old and needed updating to address EPA’s Effluent Limitation Guidelines published on December 1, 2009, advancements in technology, and issues that have been identified by stakeholders (e.g. private sector consultants, other governmental agencies, etc.) that use the document.

A copy of the draft technical standard is available on NYS DEC’s website at: http://www.dec.ny.gov/chemical/41392.html.

Written comments on the draft standard must be submitted by close of business on March 25, 2016 to: Stormwater_info@dec.ny.gov or the contact listed below. Note: If submitting comments by e-mail please indicate “Blue Book Updates” in the “Subject” line.

Contact: Dave Gasper, NYS DEC – Division of Water, 625 Broadway, 4th Floor, Albany, NY 12233-3505, E-mail: Stormwater_info@dec.ny.gov.

Phase I, promulgated in 1990, addresses the following sources:

• “Large” and “medium” Municipal Separate Storm Sewer Systems (MS4s) located in incorporated places and counties with populations of 100,000 or more and
•Eleven categories of industrial activity, one of which is large construction activity that disturbs 5 or more acres of land.

Phase II, promulgated in 1999, addresses additional sources, including MS4s not regulated under Phase I, and small construction activity disturbing between 1 and 5 acres.

The Town of Dryden, on January 1 st, 2008 became responsible for administration and enforcement of the Phase II Stormwater Management previously administered by the New York State Department of Environmental Conservation, (NYSDEC). The NYSDEC will still administer their program, but stormwater plans must first be reviewed and approved at the local level in accordance with our local law . After local review and approval the Notice of Intent and the plan must be submitted to NYSDEC.

Town of Dryden Stormwater Law

Stormwater Management is required for construction sites that disturb as little as 5,000 square feet of area, and possibly less on sensitive sites (A Notice of Ground Disturbance Form must be completed before every project). These standards / practices are designed to confine the construction site stormwater, water borne pollutants, and sediment via effective erosion and sediment control and stormwater retention structures.

Here are the Notice of Ground Disturbance Form, Summary of Town Requirements, and generic site plans for erosion and sediment control. The site plans are for small sites and portray different site characteristics such as slope or presence of wetlands or other waterbodies.

Typically, if a project does not disturb (remove or cover existing vegetation) over 5,000 square feet then it is exempt from these requirements. A Notice of Ground Disturbance must be completed in order to determine the area of disturbance, presence of sensitive features on site, and thereby the level of Stormwater Pollution Prevention Plan (SWPPP) (Simple, Basic, or Full). As always there are exceptions. Generally exceptions will involve soil & related stockpile areas, severe slops, protected water surfaces, and sensitive environmental resources, on sites smaller than 5,000 square feet that require basic measures of protection. The Town Stormwater Management Officer can assist you with identification of exceptions.

If your project creates an area of disturbance greater than 43,560 square feet (1 acre) the project needs a Basic SWPPP (Erosion and Sediment Control Plan) prepared by a Certified Professional. If the project disturbs greater than 5 acres it is subject to a Full SWPPP (Erosion and Sediment Control Plan and Post Construction Water Quality and Quantity treatment). Please see the attached Summary sheet.

For larger projects, or for assistance filling out the Notice of Ground Disturbance you should make an appointment with this office at 607-844-8888, 8:00 AM – 4:00 PM, Monday – Friday to discuss the project prior to any site disturbance.

Why Is Stormwater a Problem?

-Impervious surfaces and disturbed land contribute to changes in quality and quantity
-Pollutants include sediments, nutrients, bacteria, chemicals, metals, etc.
-Problems include scouring, temperature changes, siltation, fish kills, shellfish bans, etc.

Remember, only rain down the drain!

In developed areas, we need to commit to ‘Best Management Practices’ to minimize the risk of contamination.
