EDMS Multi-sector general permit (MSGP) NOI Modification

Instructions for completing the modification form for Storm Water Discharges Associated with Industrial Activity under the Multi-Sector General Permit (MSGP) using EDMS.

DO NOT ENTER INFORMATION FROM THE ORIGINAL NOI. You will be presented with the information DEC has on file. Review and edit/update only the information you wish to change. Certify and submit to DEC for review and processing.

Contact Information

Enter the name of the contact person, title, and the legal name of the firm, public organization, or any other entity that operates the facility described in this application. An operator of a facility is a legal entity that controls at least a portion of site operations and is not necessarily the site manager. Enter the operator’s mailing address, telephone number, and e-mail address. Correspondence for the NOI will be sent to this address.

Enter contact information for the Applicant (Responsible Official), SWPPP contact, and Application preparer, and Billing contact. Enter the name of the contact person and the legal name of the firm, public organization, or any other public entity that is responsible for accounts payable for this facility. Correspondence for billing purposes will be sent to this address. See 18 AAC 72.956 for applicable authorization fee to be paid with the submittal of the NOI.

Multiple roles may be selected per contact.

Facility Information

Indicate whether the facility has been previously covered by an APDES DEC permit. If “Yes” enter the permit authorization number that the facility was covered under.

Enter complete street address, including city, state, zip code, and county or similar government subdivision of the facility. Do NOT use a P.O. Box. If the facility lacks a street address, indicate the general location of the site (e.g., Intersection of State Highways 61 and 34). Complete facility location information must be provided for permit authorization to be granted.

Select correct borough for facility location.

Enter the latitude and longitude of the facility in decimal degrees format with up to 6-digit accuracy. You can obtain your facility's latitude and longitude through Global Positioning System (GPS) receivers, internet map service, U.S. Geological Survey (USGS) quadrangle or topographic maps, or EPA’s web-based siting-tools, among other methods. For consistency, DEC requests that measurements be taken from the approximate center of the facility.

Select the method used to determine geographic coordinates.

Select the North American Industry Classification System code (NAICS) that best describes the primary activity your facility is primarily engaged as defined in MSGP Appendix D.

Select the Standard Industry Code (SIC) code that best describes the primary activity your facility is primarily engaged as defined in MSGP Appendix D.

Enter the estimated area of industrial activity at your facility exposed to storm water, in acres. Indicate to the nearest tenth of an acre. Note: 1 acre = 43,560 sq. ft.

Indicate whether your facility is a federal facility.

Enter a brief description of the nature of the industrial activities at the facility.

MS4 and Effluent Limit Information

If you discharge into a MS4, you must identify the waterbody into which that portion of the storm sewer discharges and provide the name of the MS4 operator. Select the name of the MS4 operator.

If you are requesting permit coverage for any storm water discharges subject to effluent limitation guidelines, select the applicable 40 CFR Part/Subpart.

Indicate if you are a Sector S (Air Transportation) facility, and you anticipate using more than 100,000 gallons of glycol-based deicing/anti-icing chemicals and/or 100 tons or more of urea on an average annual basis.

Indicate whether your facility is currently inactive and unstaffed. If so then indicate whether your facility will be inactive and unstaffed for the entire permit term; or, if not, specify the specific length of time in units of days, weeks, months, or years (e.g., 3 months) that you expect the facility to be inactive and unstaffed.

SWPPP Documents

Your SWPPP is to be submitted with the NOI as required in Part 5 of the MSGP. You must keep a copy of your SWPPP on-site or otherwise make it available to facility personnel responsible for implementing provisions of the permit.

Discharge Information

You must identify all the outfalls from your facility that discharge storm water. Each outfall must be assigned a unique 3-digit ID (e.g., 001, 002, 003). You must also provide the latitude and longitude for each outfall from your facility. Indicate whether any outfalls are substantially identical to an outfall already listed and identify the outfall it is identical to. For each unique outfall you list, you must specify the name of the first water of the U.S. that receives storm water directly from the outfall and/or the Municipal Separate Storm Sewer System (MS4) that the outfall discharges to.

Your receiving water may be a lake, stream, river, ocean, wetland, or other waterbody, and may or may not be located adjacent to your facility. Your storm water may discharge directly to the receiving water or indirectly via a storm sewer system, an open drain or ditch, or other conveyance structure. Do NOT list a man-made conveyance, such as a storm sewer system, as your receiving water. Indicate the first receiving water your storm water discharge enters. For example, if your discharge enters a storm sewer system that empties into Trout Creek, which flows into Pine River, your receiving water is Trout Creek, because it is the first waterbody your discharge will reach. Similarly, a discharge into a ditch that feeds Spring Creek should be identified as “Spring Creek” since the ditch is a manmade conveyance. If you discharge into a MS4, you must identify the waterbody into which that portion of the storm sewer discharges and provide the name of the MS4 operator. That information should be readily available from the operator of the MS4. If you are uncertain of the MS4 operator, contact DEC Division of Water for that information.

You must specify whether any receiving waters that you discharge to are listed as “impaired” as defined in Appendix C, and the pollutants for which the water is impaired. You must also check/identify any Total Maximum Daily Loads (TMDL) that have been completed for any of the waters of the U.S. that you discharge to. You must also provide information about the outfall latitude/ longitude. Further information regarding impaired waters and TMDLs can be found at https://dec.alaska.gov/water/water-quality/integrated-report/.

If you are subject to any benchmark monitoring requirements for metals (see the requirements applicable to your Sector(s) in Part 11 of the permit), indicate the hardness for your receiving water(s). See Appendix E of the permit for information about determining waterbody hardness.

If you are subject to benchmark monitoring requirements for hardness-dependent metals, you must also answer whether your facility discharges into any saltwater receiving waters.

Sector/Subsector Information

Select the Sector and Subsector that apply to each outfall.
