3 Overview Manual Introduction Stormwater is rain that flows over hard surfaces and landscapes that does not infiltrate into the ground. Stormwater picks up pollutants, such as sediment, trash, animal waste, fertilizers, oils, hydrocarbons, and grease, as it moves over these surfaces. Stormwater then enters curb inlets, passes through a network of underground pipes, and dumps into local rivers. City of Bozeman staff works to improve the quality of stormwater to ensure local waterways stay clean enough to fish, recreate, and swim in. One of the largest sources of pollution staff encounters is uncontrolled stormwater runoff from construction sites. Uncontrolled stormwater runoff from construction sites displaces and deposits sediment and other pollutants offsite, causing degradation of rivers and infrastructure. A one-acre construction site can lose tons of sediment per year. This manual provides numerous approved best management practice (BMP) options for contractors, project owners, and engineers to mitigate adverse impacts and meet local requirements. 3

4 Overview Local Requirements The City of Bozeman requires that project owners submit one of the following stormwater permits before initiating ground disturbance activities. Stormwater staff highly encourages project owners or their agents to set up a pre-submittal meeting, which includes a conversation regarding minimum expectations, recommendations, and areas of concern saving both parties preparation and review time. Stormwater staff review, comment on, and, when deemed adequate, approve all permits. Project owners that do not submit or submit inadequate permits will experience a delay in building permit issuance, site plan approval, or notice to proceed until an approved permit is in place. Single-family home construction: Project owners must submit a Drainage and Stormwater Self-Certification with their building permit application. There is no fee associated with this permit. Multi-family, commercial, utility, demolition, and paving projects with a total land disturbance less than one acre: Project owners must submit an Erosion and Sediment Control Construction Permit for Projects Less than 1 Acre. There is no fee associated with this permit. Multi-family, commercial, utility, demolition and paving projects with a total land disturbance greater than one acre: Project owners must submit a Montana Department of Environmental Quality Notice of Intent, Stormwater Pollution Prevention Plan, and a Notice of Termination. There is no City of Bozeman fee associated with this permit. 4

5 Overview Minimum Standards The City of Bozeman requires that project owners meet the following minimum standards when preparing and enacting a stormwater permit for their site. Minimum standards exist to provide a consistent message to contractors, improve permit content, and promote cleaner sites. Project owners must: 1. Protect inlets: Inlets receiving site runoff require BMPs that filter stormwater before flowing into underground infrastructure. Approved options include drop inlet protection (pg. 14). 2. Contain disturbed areas: Project boundaries require BMPs that contain stormwater flowing from disturbed areas. Approved options include wattle (pg. 8), silt fence (pg. 10), and compacted earthen berm (pg. 12). 3. Mitigate tracking: Exit points require BMPs that prevent the tracking of debris offsite. Approved options include angular rock and a cattle guard/rock hybrid trackpads (pg. 16). 4. Control concrete waste: Concrete activities require BMPs that allow for the capture and disposal of generated pollutants to prevent environmental contamination. Approved options include reusable/disposable products, prefabricated roll-offs or containers, lined below-ground containment, and lined above ground containment (pg. 22). 5. Contain material stockpiles: Material stockpiles, not already contained within an existing perimeter control, require perimeter BMPs that prevent erosion and displacement of loose material. Approved options include wattle (pg. 8), silt fence (pg. 10), compacted earthen berm (pg. 12), and tarps/plastic sheeting. 6. Manage dewatering flows: Pumping activities require BMPs that filter water before entering underground infrastructure or waterways. Approved options include a series of inline treatment BMPs, land application, or wells (pg. 19). Dewatering discharges to state waters are a permitted activity under the authority of the MDEQ. 7. Protect post-construction stormwater features: Post-construction stormwater features, such as retention and detention ponds, require BMPs that protect and stabilize their side slopes and bases during and after construction activities. Approved BMPs include riprap, reinforced fore-bays, check dams, crimped straw mulch, and rolled erosion control products. 8. Stabilize disturbed areas: Disturbed areas require BMPs that prevent erosion of barren ground. Approved options include surface roughening, crimped straw mulch, wood mulch, rolled erosion control products, riprap, and sod (pg. 25). 5

6 Overview Operational and Administrative Controls Introduction Operational and administrative control BMPs help keep construction sites clean and in compliance. The following are things to consider when preparing and implementing a stormwater permit: Site Barrier Utilize site barriers to control the flow of vehicles and equipment. Several types of site barriers exist, including concrete blocks, construction fencing, and cones. Off-Site Parking Utilize off-site parking to control tracking by reducing vehicle trips onto disturbed areas. Spill Prevention and Response Utilize a spill kit to clean up leaks and spills that occur. All parties should know its location and proper use. Fleet Management Utilize inspection techniques to identify and eliminate leaks and drips of hydraulic fluid, gas, oil, etc. from equipment and vehicles. Preservation of Existing Vegetation Utilize preservation of existing vegetation techniques to reduce the amount of erodible area on a job site.
