Stormwater Department

The Stormwater Pollution Prevention Plan (SWPPP) is a plan written specific to the construction site for land disturbance activities (clearing, grading or excavation work, and similar activities) that will take place. The plan includes SWPPP and project contact information, site map and construction activities descriptions, and identifies potential pollutants and the practices used for preventing pollutants from leaving the site through stormwater runoff. The SWPPP also describes the procedures involved with inspection and maintenance of BMPs (Best Management Practices) and provides a place for these records as well as amendments and certifications to be kept.

A SWPPP is a requirement by the EPA or state construction general permit. It is generally required for sites that will disturb one acre of land or more, or for smaller sites that are part of a larger common plan of development or sale, to obtain coverage under the National Pollutant Discharge Elimination System (NPDES) for stormwater discharges.

The SWPPP plan is considered by a certified SWPPP reviewer in the Environmental Compliance Department. We try our best to review each SWPPP plan in a timely manner. The process may take 14 business days to complete.

The NOI (Notice of Intent) is the application form filed. The NOI permit is required for sites disturbing one acre or greater, and for sites disturbing less than one acre if part of a larger common plan of development or sale. Once your project is complete and the final stabilization requirements have been met, the Notice of Termination (NOT) form may be submitted to the state to terminate your permit. Please contact us today with any stormwater management questions you may have.

Best Management Practices (BMPs) measures utilized to prevent pollutants from leaving the site via stormwater discharge. There are both structural and non-structural BMPs, including but not limited to: silt fence, fiber roll, inlet protection, picking up trash onsite and sweeping the surrounding streets.

Yes. For smaller sites permitted under the Utah Common Plan Permit, inspector certification is not required. The Construction General Permit (CGP) requires the inspector to be certified.

Illicit Discharge Detection and Elimination (IDDE), a program that aims to protect waterways from pollution. Illicit discharges are substances other than stormwater that are dumped, spilled, emitted, or disposed of which could get into a municipal separate storm sewer system.

Examples of stormwater pollutants are:

•             Cleaning Supplies

•             Construction Wastes (debris, sludge, etc.)

•             Non-Residential Vehicle Wash

•             Paint

•             Vehicle Fluids (oil, anti-freeze, transmission fluid, fuel, etc.)

•             Pet Waste

•             Lawn Care (grass clippings, fertilizers, herbicides, pesticides, etc.)

The Environmental Compliance department monitors the blasting that occurs at the two open pit mines located on S.R. 73. We monitor three criteria:

•             Vibration

•             Air overpressure and/or noise levels

•             Fugitive Dust/Opacity (The quality of being difficult to see through or the degree to which something blocks light.)

Yes, blasting is allowed in Eagle Mountain, with specific criteria and restrictions. The two main restrictions are:

• No blasting may be within 1,320 feet of any residential structure without city council approval.
• Between the hours of 9 a.m. and 5 p.m.
