The New York State Department of Environmental Conservation (NYSDEC) has prepared the new SPDES Multi Sector General Permit for Stormwater Discharges from Industrial Activity (GP-0-12-001) (PDF) (1.3 MB). The new permit is effective on October 1, 2012 and will replace the current Multi Sector General Permit for Stormwater Discharges Associated with Industrial Activity (GP-0-11-009) which expired on September 30, 2012. The SPDES Multi Sector General Permit for Stormwater Discharges Associated with Industrial Activity (GP-0-12-001) is five year permit that will cover discharges of stormwater to surface waters of the State from industrial activities as defined in 40 CFR Part 122.26(b)(14)(i thru ix and xi).

Potentially regulated facilities must prepare a stormwater pollution prevention plan (SWPPP), notify DEC that they intend to be covered by the MSGP, and comply with the general and sector-specific requirements of the permit. Major changes to the MSGP include new technology-based effluent limits, additional requirements for discharges to impaired waters, changes to the best management practices options for certain sectors, and lower benchmark monitoring cutoff concentrations. DEC also reformatted the permit and various required forms and made numerous other changes. Facilities subject to the prior MSGP must revise their SWPPPs to conform to the new permit and submit a new Notice of Intent form requesting coverage under the permit by Decemeber 31, 2012.

To reduce the level of effort required for facilities to come into compliance with new permit requirements, Caltha LLP has prepared a SWPPP template based on the revised New York permit requirements, including New York specific quarterly inspection checklist, quarterly visual assessment checklist, quarterly benchmark monitoring checklist, and an annual comprehensive site inspection checklist. Caltha has also prepared a New York Stormwater Permit Compliance Plan to assist permitted facilities in organizing and planning new compliance requirements under the DEC general permit.
