The city's Stormwater Management Program is dedicated to protecting the quality of our surface waters, ponds, creeks, and rivers.
The Stormwater Management Program complies with the National Pollutant Discharge Elimination System (NPDES) under the Federal Clean Water Act. The program includes:
- compliance with the city's NPDES permit and annual reporting to the State Water Quality Control Board
- enforcement procedures
- inspections for illicit discharge and connections
- monitoring stormwater runoff
- public awareness and education programs for residents, developers, contractors, businesses, and municipalities
The city's Stormwater Pollution Prevention policy is found in Title 3, Chapter 7 of the City of Montrose Municipal Code.
Permit for Construction
Stormwater Construction Permit (https://www.colorado.gov/pacific/cdphe/wq-construction-general-permits) coverage is required by state and federal regulations for stormwater discharges associated with any construction activity within city limits that disturbs at least one acre of land or is part of a larger common plan of development or sale that will disturb at least one acre of land. A “common plan of development or sale” is defined as a contiguous area where multiple separate and distinct construction activities may be taking place at different times and on different schedules, but remain related (such as a residential or commercial subdivision, even if individual lots are less than one acre).
Reporting Illegal Discharge
