Site Data
Location:
Velocity Carwash
3100 West Main Street
Bozeman, MT
Responsible Party for Maintenance:
Velocity Carwash, the owner of the property and shall be required to keep a log of all required inspections
and maintenance required. The log shall be made available to the City of Bozeman Public Works
Department for review as requested.
Land Use & Site Area:
The project site is located at 3100 West Main Street and zoned B-2 – Community Business District. The
site consists of one building with an asphalt parking lot. The site will be landscaped according to approved
landscaping plans and must meet the City of Bozeman Unified Development Code.
Storm Water Management Systems:
The storm water management system includes a system of inlets and piping that routes stormwater runoff
to an underground retention chamber system in the parking lot.
Inspection & Maintenance
Storm water facilities and permanent Best Management Practices (BMPs) must be inspected in
accordance with this document. All documentation on scheduled inspections, times of inspections,
maintenance completed, remedial actions taken to make repairs, and any modifications or reconstruction
of the storm system shall be maintained on-site.
Disposal of the accumulated sediment must be in accordance with all applicable local, state, and federal
guidelines and regulations. If any drainage structure or outfall indicates the presence of petroleum, the
petroleum material shall be removed and disposed of immediately in accordance with applicable
regulations. All estimated costs are based on labor rates assumed in 2025.

Pavement Sweeping & Vacuuming:
All paved areas shall be swept twice a year, scheduled in spring and fall.
Estimated Annual Cost: $500
Strom Drain Inlet/ Sump
The inlets shall be inspected to ensure they have adequate sump capacity, the grate is in place, secure
and free of debris, the frame and grate are not damaged, and internal concrete and grout is intact.
Inspect the inlets four times per year and following large storm events.
Clean sumps annually or whenever sumps become filled with sediment to half its depth (1’-0”).
Estimated Cost: $500
If inspection indicates the presence of petroleum, the petroleum material shall be removed and disposed
of immediately in accordance with applicable regulations.
Storm Drain Inlet Expected Design Life: If regular maintenance is performed, the storm drain inlet can be
expected to last for 50 to 100 years.
Expected Replacement Cost: $5,000
Underground Retention System (Stormtech Chambers):
All storm drain pipe shall be inspected for any damage and/or blockages.
Inspect piping annually and following large storm events.
If excessive sediment is determined to exist in the pipe, it shall be removed through jetting and flushing.
Estimated cost: $1,000
After major storm events, monitor the system to ensure the runoff is infiltrating into the ground and completely
draining within 72 hours after cessation of the storm. If the systems appear to be clogged, consult with an engineer
or other qualified professional to evaluate the system and determine whether it needs to be replaced. If the retention
system becomes clogged, the entire system must be replaced. Regular maintenance and sedimentation prevention
greatly increases the life of the system.
Underground Retention Expected Design Life: 50+ years if regular maintenance is performed.
Expected Replacement Cost: $20,000 to $30,000

Housekeeping Operations
Good housekeeping and material management reduces the risk of spills or other accidental exposure of
materials and substances to storm water runoff.
All materials stored on-site must be stored in a neat, orderly manner in their appropriate containers and, if possible,
under a roof or other enclosure.
Products shall be kept in their original containers with the original manufacturer’s label.
Substances should not be mixed with one another unless recommended by the manufacturer.
Whenever possible, all of a product will be used up before disposing of a container.
Original materials labels and material safety data sheets (MSDS) shall be kept by the Owner.
Petroleum products:
All on-site vehicles and parking areas shall be monitored weekly for leaks and spills. Spills shall be cleaned
immediately.
Petroleum products shall be stored under cover and shall be in tightly sealed containers that are clearly labeled.
Fertilizers:
Fertilizers shall only be used in the minimum amounts as recommended by the manufacturer.
The contents of any unused fertilizer shall be transferred to a clearly labeled, sealable plastic bin to avoid
spillage.
Paints solvents.
All paints and solvents shall be stored in original manufacturer’s containers in a covered location.
The use of paints and solvents shall, whenever possible, be limited to service or storage bays. Where not
possible, the work area shall be protected with impermeable drop clothes or tarps. At no point shall material be
used in parking or access ways that are tributaries to the drainage system.
Spill Control Practices
Manufacturer's recommended methods shall be clearly posted for spill clean-up and hotel personnel shall be made
aware of the procedures and the locations of cleanup information and supplies.
Material and equipment necessary for spill clean-up will be kept on-site in a designated material storage area.
Equipment will include, but not be limited to, brooms, dust pans, mops, rags, gloves, goggles, absorbent materials,
sand, sawdust, and plastic & metal trash containers specifically kept and labeled for this purpose.
All spills must be cleaned-up immediately after discovery.
Spills of toxic or hazardous material must be reported to the appropriate state, local, or federal agency, as required
by-law.
Winter Maintenance Activities
Snow plowing operations shall stockpile snow, ice and accumulated materials in areas where snow melt will flow into
the on-site drainage systems, including drainage basins.
During winter conditions sand use site-wide shall be applied to the minimum extent possible to maintain safe
conditions.

The usage of sodium chloride or chloride containing materials for snow and ice removal is not recommended so as to
avoid the introduction of salts to the storm water management system.
Repair Procedures
Grass Swales, Dense Weeds or Sparse Grass Cover
Re-seed or sod the area, but first determine and address the source of the problem. Expand irrigation coverage,
add soil amendments, fertilize, etc., as needed to improve growth media and grass health.
Grass Swales, Areas of Ponding
Cut sod and re-grade the area for consistent downgradient slope along the swale. Then re-seed or sod the area
of disturbance.
