Other pollutants must be
contained to prevent them from polluting stormwater, including:
- Petroleum products
- Antifreeze
- Cleaning agents
- Solvents
- Pesticides/herbicides
- Dirt
- Grass clippings
- Unknown chemicals
The State of Colorado requires
sites to obtain a State stormwater discharge permit for
construction activity and to develop a Construction Storm
Water Management Plan (SWMP) to control construction site
pollutants. The State permit application and SWMP guidance
can be found at the CDPHE web site at: http://www.cdphe.state.co.us/wq/PermitsUnit/SWConstructionApplication.pdf
Grand Junction's Stormwater Construction Permit
requires a Construction Stormwater Management Plan be submitted
for City review and approval according to the Stormwater
Management Manual (SWMM) requirements.
Grand Junction is
issuing Storm Water Construction Permits to sites greater
than one acre in size. To view and print the City of Grand
Junction Stormwater Permit Application, click here: Stormwater
Construction Permit Application
For projects > 1 acre in size that disrupt soils, the
Stormwater Construction
Permit Field Inspection Report is required to be filled
out by a qualified inspector every 14 days and after each
rain event that causes surface runoff. City inspectors will
be auditing construction sites to assure the form is completed.

Construction Construction Permitting Process
Before construction
starts
Before you clear, grub,
or start construction on a site larger than one acre in
size, you must obtain a Stormwater Construction Permit from
the City of Grand Junction. You must provide:
- a copy of the State
of Colorado Stormwater Discharge Permit
- a Construction Storm
Water Management Plan (CSWMP) that has been approved by
the City of Grand Junction
- Major modifications
to the CSWMP must be approved by the City's Development
Engineer
- Minor modifications
do not need approval, but must be recorded on the CSWMP
and kept on the construction site
After construction starts
Permittees are required
to inspect the construction BMP's at least once every 14
days and after any weather event that results in surface
runoff.
Grand Junction will inspect
your construction site for compliance with the CSWMP requirements.
You will receive an invoice billed at $45 and hours for
the City inspection. All permit and CSWMP violations are
expected to be corrected or a municipal fine may be imposed.
Controlling
pollutants from your construction site ensures good water
quality for future generations.
A glossary of terms:
BMP: Best Management Practices.
Those measures that will
ensure that stormwater does not become polluted. These
can include silt fencing, straw bales, sediment traps, temporary
berms, etc.
SWMP: Stormwater Management Plan
A written plan for the
State that outlines specific measures will be taken on the
construction site and following construction to ensure that
stormwater coming off the site is not polluted.
CSWMP: Construction Stormwater Management Plan
A written plan submitted
to the City of Grand Junction that outlines specific measures
that will be taken on the construction site to prevent polluted
stormwater from leaving the site during and after construction.
CDPHE: Colorado Department of Health and Environment
The state agency that regulates
stormwater pollution in Colorado and issues permits.
