CONSTRUCTION STORMWATER MANAGEMENT (SWPPP Program and Long-Term Management)

A State Permit (UPDES) is a requirement to control and eliminate stormwater pollution sources on land disturbance sites through the development and implementation of a SWPPP. There are 2 types of State Permits, they are:

  • Common Plan Permit (CPP)- applies to single residential lots disturbing less than an acre and located in subdivisions that are an acre or greater that were subdivided post October 1992.
  • Construction General Permit (CGP)- applies to all other lots disturbing an acre or more (or lots that are part of a common plan of development, subdivision, or phased project that disturb an acre or more).

These UPDES Permits require a Stormwater Pollution Prevent Plan (SWPPP) to be developed and reviewed/approved by the City through the City's building permit process prior to the issuance of a building permit. Refer to Municipal Code 13-4 to review City regulation and enforcement of stormwater discharges associated with construction activities.

Refer to: Stormwater Pollution Prevention Plans FAQs, for more step-by-step information on acquiring your State CGP/CPP Permits and SWPPP Submittal Process.

NOI Process: 

Apply for a State permit. Also known as filing a Notice of Intent (NOI).  State permits are filed through the State of Utah.

  • If you have not applied for a State permit before, create an account with the State of Utah.  Create an account early because it can take a while to receive login credentials.  
  • Part of the SWPPP requirement is an active State permit, be sure to file an NOI with the State of Utah and submit with your SWPPP for review.

**To avoid delays, note the following**

  • Choose the NOI for the type of State permit that applies to your project.
  • Ensure the person who will be signing and submitting forms applies as a Signatory (not Preparer).
  • Use full legal names and home addresses.
  • Read and understand all requirements of the State permit that covers your project.  The State of Utah Department of Environmental Quality (DEQ) or EPA may inspect your project at any time without notice.
  • REMINDER: State permits are active for one year from the date you apply.  Renew as needed, until Notice of Termination (NOT) is requested.

SWPPP Inspections:

Park City utilizes UtiliSync for City SWPPP inspections and also provides contractors the opportunity to use the platform for their inspections. Once your SWPPP is approved and a pre-construction meeting has taken place, you will receive an invitation link via email. Refer to the UtiliSync Guide for additional assistance.

NOT Process: 

Request termination of the State permit. Also known as filing a Notice of Termination (NOT) once these conditions have been met:

  • All temporary storm water control measures have been removed.
  • The site has achieved final stabilization.
  • All construction materials, waste, and equipment have been removed.
  • All potential pollutants and pollution-generating activities have been removed.

The operator will request through NeT, a Notice of Termination (NOT). The MS4 authority will be notified of the request to approve the operators NOT. Once all work is complete and vegetation is stabilized, the NOT can be closed out. Contact SWPPP Coordinator, Christine Williams at 435-615-5364 or christine.williams@parkcity.org for any questions, such as:

  • Verify the State permit termination process can begin.
  • Determine when to request an NOT with the State of Utah.
  • Schedule the SWPPP Final Inspection. NOTE: SWPPP Final inspection requirements are provided with the State permit that covers your project. Read and understand all requirements.
  • Receive long term inspection requirement instructions, if applicable.

REMINDER: State permits are active for one year from the date you applied. Renew as needed, until NOT is requested.

Long Term Stormwater Management

Park City's MS4 Permit requires the City to implement regulatory mechanisms that manages runoff from development. Municipal Code 13-5 was adopted to achieve compliance with Long Term Stormwater Management with the State MS4 Permit. This requires all new developments and redevelopments to create a Long-Term Stormwater Management Plan (LTSWMP) and sign a Maintenance Agreement that is recorded with the County. 

This LTSWMP explains the layout of the property and how the property owner is going to maintain their property to reduce pollutant runoff. Inspections are also required every other year by the property owner of the Site, and The City will perform an inspection every 5 years to ensure the plan is effective. These inspections will be performed in Utilisync. The Stormwater Coordinator will send out invitation links and reminder emails through UtiliSync to Maintenance Agreement holders to complete quick and easy inspections.

Long Term Stormwater Requirements: 

Two (2) attachments must be included when submitted, an Agreement and a Plan:

Park City LTSWM Maintenance Agreement - this is the Maintenance Agreement that needs to be signed by the property owner. It will be recorded with the County. 

-and one of the following-

Park City LTSWM Plan Template - this is the LTSWMP template for large, non-residential projects. This is meant to be used as a template and modified as needed to conform to the Site. This Plan will be recoded with the County and will act as a living document as site conditions change.

-OR-

Park City LTSWM Plan (minor residential) Template - this is the LTSWMP template for small, residential projects. This is meant to be used as a template and modified as needed to conform to the Site. This Plan will be recoded with the County and will act as a living document as site conditions change.

The owner of the property must sign the agreement and have and have their signature notarized. The signature must match the owner listed on the Title Report.

An original signed agreement must be submitted.

This cannot be stapled or double sided.

PROCESS:

  • The applicant will submit completed LTSWM Agreement to the Engineering Department.
  • Water Department approval.
  • Engineering Department approval.
  • Engineering Department will mail the agreement to Summit County to be recorded.
