Multi-Sector General Permit (MSGP)

The Department is currently finalizing the renewal Multi-Sector General Permit (GP-0-17-004). Please do not submit an NOI to continue coverage until the permit and the new NOI are posted on the website. The NOI for GP-12-001 has been removed and is no longer available to gain coverage under the MSGP.

Permit (GP-0-12-001)

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 (5) 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).

The Annual Certification Report for the Multi-Sector General Permit (GP-0-12-001) can now be completed online through the NYSDEC eBusiness Forms Portal.

Permit Background

The Clean Water Act provides that stormwater discharges associated with industrial activity to waters of the United States (including discharges through a municipal separate storm sewer system) are unlawful, unless authorized by a National Pollutant Discharge Elimination System (NPDES) permit. In New York, EPA has approved the state program which is enacted through the administration of the State Pollutant Discharge Elimination System (SPDES) program. Industrial facilities engaged in activities defined in 40 CFR 122.26(b)(14)(i-ix) and (xi) must obtain permit coverage for stormwater discharges to waters of the United States through either an individual industrial SPDES permit, the SPDES Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activity, or provide certification using the No Exposure Exclusion that industrial activities are not exposed to stormwater.

Frequently Asked Questions

What is the difference between the MSGP and an individual permit?

The MSGP is a general permit. Rather than addressing environmental concerns for a single facility as an individual permit does, the Multi-Sector General Permit includes conditions and requirements that are applicable to 31 categories of industrial activities. Unless otherwise notified by the Department, stormwater discharge(s) from facilities engaged in one or more of these categories are eligible for coverage under MSGP.

All facilities that have gained coverage under MSGP must comply with the general requirements included in Parts I through VII of the permit. In addition to the general requirements, a permittee must comply with specific requirements applicable to the activities being conducted at the covered facility. These sector-specific requirements are found in Part VIII of the permit. For instance, all truck maintenance facilities covered under MSGP must comply with the general conditions in Parts I through VII as well as the requirements in Part VIII.P.

Which industrial facilities are eligible for coverage under MSGP?

The list of Standard Industrial Classification (SIC) codes and other descriptions of activities included in 40 CFR 122.26 (b)(14)(i))-(xi) are found in Table I-1 (beginning on page 4) of the MSGP (GP-0-12-001). Facilities with primary industrial activities included in the table are eligible for coverage under MSGP unless otherwise notified by the Department. Additionally, under Sector AD of the MSGP, the Department may grant eligibility to facilities with stormwater discharges from other types of industrial activities as an alternative to individual permit coverage. In such cases, the Department assigns activity-specific SWPPP and monitoring requirements, which are developed to appropriately address potential sources of contamination to stormwater. As with other sectors, the activity specific requirements must be met in addition to the conditions and requirements in Parts I through VII of GP-0-12-001.

  • Primary Industrial Activities:
    A facility's primary industrial activity is the activity that employs the most personnel and/or generates the most revenue. If the facility is part of a larger company, the SIC code associated with the primary industrial activity at a particular facility may be different than that used by the corporation.
  • Co-located Activities:
    Some facilities may have more than one activity requiring coverage under MSGP. These are called co-located activities. A facility with a primary industrial activity that is required to obtain coverage under MSGP is also required to comply with requirements that apply to other activities at the facility if those additional activities would require coverage if considered on their own.
    If more than one activity listed in Appendix B of GP-0-12-001 is being performed at a facility, all SIC codes must be included in the NOI submitted to the Department to gain or renew coverage under MSGP. There are specific monitoring and SWPPP requirements associated with each industrial sector. Permittees must comply with all requirements related to each activity.

The United States Department of Labor has a Standard Industrial Classification (SIC) Code System Search that can help identify or confirm a facility's SIC code(s). This off-site link can be accessed through the link on the right hand site of this page.

Not all of the industrial activities included in 40 CFR 122.26 (b)(14)(i))-(xi) are defined by SIC codes. Refer to Appendix B of GP-0-12-001 for a complete list of covered activities.

MSGP does not authorize non-stormwater discharges or stormwater discharges mixed with non-stormwater discharges, unless the source of non-stormwater is included in Part I.C.3.

Is coverage required if no operations or materials are exposed to precipitation?

A No Exposure Exclusion from MSGP coverage is available if all industrial materials and activities are protected by a storm resistant shelter to prevent exposure to rain, snow, snow melt and/or runoff. In order to obtain a waiver, a facility must submit a No Exposure Certification form - 2005 (PDF, 47 KB) certifying a condition of No Exposure. A condition of No Exposure must be re-certified every five years. If, after receiving a waiver, operations change in such a way that No Exposure criteria are no longer met, the facility must submit a Notice of Intent (NOI) to gain authorization under MSGP at that time. More information about the No Exposure Exclusion is available at SPDES No Exposure Certification for Stormwater Permitting.
