This page provides guidance for completing the Municipal Separate Storm Sewer System Application Form. Completing and submitting this form is a requirement for permittees who have Total Maximum Daily Load (TMDL) Wasteload Allocations (WLAs) for total phosphorus, total suspended solids, oxygen demand, or nitrate.

Description of the form

Each MS4 Permit TMDL Application Form is a custom created workbook for each permittee with United States Environmental Protection Agency (USEPA) approved Total Maximum Daily Load (TMDL) wasteload allocations (WLAs). The workbook consists of eight tabs. Three tabs are informational- for the permittee to reference in order to complete the MS4 Part 2 Permit Application, or to complete subsequent tabs in this workbook.

General instructions on how to complete the form, and reference links.

Bacteria Chloride Temp tab

Informational tab- lists any applicable WLAs for bacteria, chloride or temperature TMDL projects (USEPA approved, more than a zero % reduction). Use the information in this tab to answer questions 141, 146 and 151 in the MS4 Part 2 Permit Application. If there is not a project listed for any certain pollutant, you would check the 'No' box for the corresponding question(s) in the MS4 Part 2 Permit Application.

Applicable WLAs determination tab

This tab includes two separate lists. The list in Column A contains any applicable WLAs (USEPA approved, more than a zero % reduction) for oxygen demand, nitrate, TSS, or TP TMDL projects. They are listed by TMDL project name-waterbody-(waterbody id)-pollutant. Column F lists the corresponding applicable numeric WLAs for those projects. The applicant needs to make a determination if they are meeting each WLA or not and type 'Yes' or 'No' in Column B. Once the determination is made, there is a macro that needs to run, and this will autopopulate the rest of the workbook.
