Montana Law and Storm Water Permitting
15
Montana Code Annotated (MCA) 2001 n TITLE 75. ENVIRONMENTAL PROTECTION CHAPTER 5. WATER QUALITY n (29) (a) "State waters" means a body of water, irrigation system, or drainage system, either surface or underground. (b) The term does not apply to: (i) ponds or lagoons used solely for treating, transporting, or impounding pollutants; or (ii) irrigation waters or land application disposal waters when the waters are used up within the irrigation or land application disposal system and the waters are not returned to state waters.
16
Montana Code Annotated (continued) n 75-5-101. Policy. It is the public policy of this state to: (1) conserve water by protecting, maintaining, and improving the quality and potability of water for public water supplies, wildlife, fish and aquatic life, agriculture, industry, recreation, and other beneficial uses; (2) provide a comprehensive program for the prevention, abatement, and control of water pollution.
17
Montana Code Annotated (continued) 25) (a) "Pollution" means: (i) contamination or other alteration of the physical, chemical, or biological properties of state waters that exceeds that permitted by Montana water quality standards, including but not limited to standards relating to change in temperature, taste, color, turbidity, or odor; or (ii) the discharge, seepage, drainage, infiltration, or flow of liquid, gaseous, solid, radioactive, or other substance into state water that will or is likely to create a nuisance or render the waters harmful, detrimental, or injurious to public health, recreation, safety, or welfare, to livestock, or to wild animals, birds, fish, or other wildlife. (b) A discharge, seepage, drainage, infiltration, or flow that is authorized under the pollution discharge permit rules of the board is not pollution under this chapter.

Pollution Authorization
19
Storm Water Permitting Authority n Tribal Lands (EPA) n All other lands within the State of Montana (Montana Department of Environmental Quality)
20
General Permit for Storm Water Discharge associated with construction Activity (obtained from DEQ) n Part I. Coverage provided by General Permit n Part II. Effluent Limitations and Special Conditions n Part III. Monitoring, Reporting, Record Keeping n Part IV. Storm Water Pollution Prevention Plan (SWPPP) n Part V. Standard Conditions
21
General Permit Summary n Identify areas that may contribute pollutants to surface waters n Ensure that minimal sediment reaches surface water using erosion and sediment control measures n Develop and implement a Storm Water Pollution Prevention Plan (SWPPP)
22
General Permit Part I. Coverage provided n Construction disturbances >1 acre require permitting n All discharges must be in accordance with the SWPPP n Notice of Intent (NOI) Package must be submitted to DEQ n NOI Package contains standard NOI form, SWPPP and application fee
23
NOI Form n Name and address of operator(s) n Contact person telephone number n Project name and location n Name of receiving surface water n Construction schedule n Estimated area of disturbance Located on pages C-2 and D-2 of Reference Manual
24
General Permit Part II. Effluent Limitations and Special Conditions n All discharges to surface water must be composed entirely of stormwater n No discharge of process wastewater n Stormwater discharges must not cause or contribute to water quality standard violations n BMPs must be maintained in accordance with SWPPP
25
General Permit Part III. Monitoring, Reporting, Record Keeping n All erosion and sediment control measures must be inspected and maintained by the operator at least once every 14 days and within 24 hours of any storm event of 0.5 inches or greater n DEQ must be notified in writing within 2 days of the detection of any significant spill or release n Copy of SWPPP must be available on-site n Uncontrolled releases must be documented
26
“significant sediment” n Mud, dirt, sediment, or similar material exceeding 1.0 cubic foot in volume which is deposited in any area of 100 square feet or less on public or private streets or property adjacent to the construction site.
27
General Permit Part IV. Storm Water Pollution Prevention Plan (SWPPP) n Operator shall develop a SWPPP and submit a copy at the same time as the NOI form n Operator shall implement the SWPPP at the time construction activity commences n Operator is responsible for for ensuring SWPPP requirements stated in the General Permit are complied with Blank SWPPP located in Appendix E of the Reference Manual Example SWPPP located in Appendix F of the Reference Manual
28
SWPPP (continued) n The SWPPP may include any erosion and sediment control measures or BMPs including but not limited to the use of sediment basins, berms, barriers, filter strips, covers, diversion structures, seeding, and sodding
29
The SWPPP must include maps(s) indicating: n Areas of disturbance n Drainage patterns n Location of BMPs n Revegetation areas n Location of Impervious structures n Location of all surface waters n Location of 100 year floodplain
30
SWPPP (cont.) n Must include BMP description n Must preserve existing vegetation n None of temporary BMPs shall be removed until permanent vegetation and site stabilization has taken place n BMPs must minimize or prevent “significant sediment” from leaving the construction site
31
Notice of Termination (NOT) Form n Where a site has been finally stabilized the operator of a site shall submit a Notice of Termination to DEQ n “final stabilization” means all soil disturbing activities have been completed and a vegetative cover has been established with a density of at least 70 percent of the pre-disturbance levels Located on page G-2 and H-2 of the Reference Manual Appendices
32
Storm Water Compliance n DEQ expects all permit holders to be in compliance with the provisions of the General Permit and the site specific SWPPP n DEQ will conduct inspections n DEQ will issue fines for non-compliance
33
Fines for non-compliance n 75-5-631. Civil penalties (1) In an action initiated by the department to collect civil penalties against a person who is found to have violated this chapter or a rule, permit, effluent standard, or order issued under the provisions of this chapter, the person is subject to a civil penalty not to exceed $25,000. Each day of violation constitutes a separate violation.
34
Fines for non-compliance n 75-5-632. Criminal penalties. A person who willfully or negligently violates 75-5-605 or any pretreatment standard established pursuant to this chapter is guilty of an offense and, upon conviction, is subject to a fine not to exceed $25,000 per day of violation or imprisonment for not more than 1 year, or both. Following an initial conviction under this section, subsequent convictions subject a person to a fine of not more than $50,000 per day of violation or imprisonment for not more than 2 years, or both.75-5-605
