B. My construction project involves:

Disturbance of five or more acres OR
Disturbance of one or more acres and construction of any type of project other than single-family residences, such as an apartment complex, condominiums, or commercial, office or industrial buildings

The site operator must:

Develop a Full SWPPP addressing erosion and sediment control, water quality, and water quantity.
If the SWPPP conforms to the New York State Stormwater Management Design Manual
Submit a Notice of Intent based on the completed Full SWPPP to NYSDEC.
Begin construction after the five business day NYSDEC review period.

If the SWPP does not conform to the New York State Stormwater Management Design Manual

Have the Full SWPPP certified by a licensed professional (P.E., M.L.A., or CPESC/CPSWQ)
Submit a Notice of Intent based on the certified Full SWPPP to NYSDEC
Begin construction after a 60-business day review period, unless informed otherwise by NYSDEC.

The Notice of Intent (NOI) must be completed by the owner/operator of the site. The owner/operator is defined as the person(s) who has operational control over the construction project’s plans and specifications and the ability to make modifications to them, and who provides day-to-day compliance with the SWPPP or other permit controls.

A copy of the NOI, SPDES Permit GP-02-01, and the Stormwater Pollution Prevention Plan must be kept on site at all times while work is in progress. All contractors and subcontractors implementing any work under SPDES Permit GP-02-01 must sign the contractor certification statement as specified in the SPDES Permit GP-02-01

A plan must be developed for control of erosion and sedimentation during construction. This plan must show appropriate vegetative and structural measures for reducing runoff velocity, stabilizing soil to prevent erosion, and capturing eroded sediment before it leaves the site. All practices must be designed in accordance with the New York Standards and Specifications for Erosion and Sediment Control . A plan for maintenance of these practices to keep them functioning effectively should also be included.

The site should be inspected at least every seven calendar days by a qualified professional (licensed professional engineer, CPESC, or soil scientist) and within 24 hours of all storm events totaling 0.5 inches of precipitation or greater. Please see SPDES Permit GP-02-01 for full details on what is expected by NYSDEC in each site inspection. A logbook documenting the inspections and corrective action taken to rectify any problems discovered must also be kept onsite at all times. Areas where work has been completed should be stabilized as soon as practicable, but not later than 14 days after construction activity has been completed in that area (see SPDES Permit GP-02-01 for limited exceptions).

A Full SWPPP must demonstrate that the site treatment allows no increase in runoff volume from pre-construction to post-construction conditions. The Full SWPPP must include a hydrologic and hydraulic analysis to demonstrate that permanent on-site stormwater management systems provide adequate treatment of water quality and storage volumes for channel protection, overbank flooding, and extreme flood control (see the New York State Stormwater Management Design Manual for technical information about what these requirements entail, as all post-construction stormwater management controls must be designed in accordance with this Manual).

VERY IMPORTANT: NOTHING IN THE PERMIT AUTHORIZES YOU TO CAUSE OR CONTRIBUTE TO A VIOLATION OF WATER QUALITY STANDARDS!

Generally, if a visible contrast to natural conditions in a receiving stream, lake, or other water body can be observed and traced to the project, NYSDEC will consider it to be a contravention of water quality standards. This would constitute a violation of the New York State Environmental Conservation Law. This means that even if you have completed a SWPPP and are implementing it to the best of your ability, and have a Notice of Intent on file with NYSDEC, discharge of polluted water to a receiving water body, wetland, or drainage system is still a violation of the law. A SWPPP that is ineffective in preventing erosion or pollution of water resources must be amended so that it is adequate. The SWPPP must also be appropriately modified if substantive changes to the project scope, sequence, or configuration are made.
