Stormwater Industrial Requirements

National Information: Stormwater Discharge From Industrial Facilities
EPA issued the Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activities (MSGP-2008) for facilities located in Alaska and Idaho; on Indian Country lands within Idaho, Oregon, and Washington; and for federal facilities located within Washington State.

The deadline for operators in these areas to submit a Notice of Intent (NOI) under the MSGP-2008 was May 27, 2009. Electronic NOIs are the preferred method of submittal; alternatively, a paper copy of the NOI may be submitted to the address contained in the NOI instructions, as found in Appendix G of the MSGP-2008.

PLEASE NOTE: Part 9.10 of the MSGP-2008 details additional permit conditions for facilities located in the geographic areas noted below. For more information, read the updated text for Part 9 (PDF) (27 pp. 452K, About PDF).

Table 9.10-1 summarizes all NOI submittal deadline(s) and discharge authorization dates for facilities within the Pacific NW and Alaska. In general, submit your facility NOI no later than May 27, 2009. Facility operators in the following areas must update their Storm Water Pollution Prevention Plans, and comply with all relevant conditions of Part 9.10 of the MSGP-2008 as found in:

MSGP Part:
9.10.1: State of Alaska, except Indian Country lands
9.10.3: State of Idaho, except Indian Country lands
9.10.5.1: Confederated Tribes of the Umatilla Indian Reservation
9.10.6.1: Lummi Nation
9.10.6.2: Puyallup Tribe of Indians

MSGP Appendix C- Part C.10 (PDF) (5 pp. 546K, About PDF), is also updated to reflect the permit availability in Pacific Northwest and Alaska. Parts 1 through 8 of the MSGP 2008, and Appendices A, B, & D-K remain the same. Complete text of the MSGP 2008 (PDF) (5pp., 546KB).

Final 2008 MSGP (PDF) (247 pp, 2.09MB) - The 2008 MSGP includes (1) general requirements (Parts 1-7), (2) sector-specific requirements (Part 8), (3) specific State and Tribal requirements (Part 9), and definitions, general conditions, areas of coverage and eligible industries, and various forms (Appendices A-K).
Final 2008 MSGP Fact Sheet (PDF) (154 pp, 1.1MB) - The MSGP fact sheet includes a section-by-section discussion of the final 2008 MSGP, including detailed summaries of all provisions, the changes made between the 2000 MSGP and the final 2008 MSGP, and the changes made between the proposed permit and the final 2008 MSGP.
Industrial Sector Fact Sheets - These fact sheets summarize the types of facilities included in each of the 29 sectors regulated under the 2008 MSGP, the pollutants associated with this sector, and the types of stormwater control measures generally used.

Who Should Apply for Coverage under the EPA Multi-Sector General Permit?
"Storm water discharges associated with industrial activity" were defined in the federal regulations published on November 16, 1990, and can be found in the Code of Federal Regulations at 40 CFR 122.26(b)(14)(i)-(xi). EPA identifies eleven categories of industry that are required to obtain permit coverage under the NPDES Storm Water Program.

An industrial facility requires permit coverage for its stormwater discharges under two conditions: 1) the runoff enters waters of the United States or enters a municipal separate storm sewer system before draining to waters of the U.S, and 2) the facility conducts an industrial activity defined in the regulations cited above.

Use the facility's primary Standard Industrial Classification (SIC) code to determine if an industrial activity falls into one or more of the 11 categories: check OSHA's SIC Division Structure website or check the Table 1-1 of the Multi-Sector General Permit for more details.

EPA's current permit, the MSGP-2000, offers coverage for industrial stormwater discharges in all areas where EPA is the NPDES permitting authority. In the Pacific Northwest, the MSGP-2000 is effective for all areas of Idaho and Alaska; for all tribal lands in Oregon; and for all federal and tribal lands in Washington.

Facilities may be eligible to claim "no exposure," and be temporarily excluded from permitting, where industrial materials, material handling operations, and industrial processes are not exposed to storm water. To determine if your facility qualifies for this exclusion, see the "No Exposure" guidance document listed below.

Guidance Documents

EPA Memorandum on Coverage of DOT Sand & Gravel Operations Under the 2008 MSGP (PDF) (3 pp. 133K) - This guidance memo addresses how the 2008 MSGP applies to stormwater discharges from gravel pits and their associated material processing operations that are used to support road and bridge construction and/or maintenance activities.
Industrial SWPPP Guidance (PDF) (45 pp, 2.53MB) - [Final Formatted Version! (3/13/09)] Guidance on how to develop a SWPPP that meets the requirements of the 2008 MSGP.
Sample MSGP SWPPP Template (PDF) (22 pp, 355K) - Industrial facilities can now use EPA’s "Industrial SWPPP Template" to create their own SWPPPs. The Template provides step-by-step instructions for developing a SWPPP for your site, based on the requirements in the 2008 MSGP. As a reminder, all facilities must have a SWPPP completed prior to submitting their NOIs for coverage under the 2008 MSGP.
Sample Recordkeeping Templates (PDF) (21 pp, 332K) - Use the sample templates and forms in the "Additional Documentation Template" to keep records of your monitoring, inspection, maintenance, visual evaluation, and corrective action activities.
Industrial Stormwater Monitoring and Sampling Guide (PDF) (51 pp, 1.13MB) - This guide is a how-to primer for industrial operators on how to conduct visual and analytical monitoring of stormwater discharges. The guide is written to help facilities understand and comply with the 2008 MSGP monitoring requirements, but can also be used by facilities subject to different state permits.
MSGP Industrial Discharge Monitoring Report (MDMR) Form (4 pp, 282K) - Permittees unable to access the eNOI reporting system can use this paper form to submit analytical monitoring results to EPA. You may also use this paper form as a checklist for the information you will need when submitting a MDMR electronically via EPA’s eNOI system. Note: Even though this publication is a PDF file, it allows you to type directly onto the form while it is open in the Adobe Acrobat Reader.
Annual Reporting Form (PDF) (6 pp, 484K) - Permittees are now required to submit to EPA annual reports summarizing their annual comprehensive site inspection and corrective actions taken during the year. EPA has developed this Annual Reporting Form, which can be used by permittees to submit this information to EPA.
Questions and Answers about the MSGP 2008 (PDF) (26pp., 246KB) - This document provides answers to many of the commonly asked questions here in Region 10 about the 2008 MSGP.
