TITLE 75. ENVIRONMENTAL PROTECTION CHAPTER 5. WATER QUALITY

(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.

Montana Code Annotated (continued)Montana Code Annotated (continued)

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.

Montana Code Annotated (continued)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.

General Permit Part II. Effluent Limitations and Special ConditionsGeneral Permit Part II. Effluent Limitations and Special Conditions

All discharges to surface water must be composed entirely of stormwater

No discharge of process wastewater

Stormwater discharges must not cause or contribute to water quality standard violations

BMPs must be maintained in accordance with SWPPP

General Permit Part III. Monitoring, Reporting, Record KeepingGeneral Permit Part III. Monitoring, Reporting, Record Keeping

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

DEQ must be notified in writing within 2 days of the detection of any significant spill or release

Copy of SWPPP must be available on-site

Uncontrolled releases must be documented

“significant sediment”“significant sediment”

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.

General Permit Part IV. Storm Water Pollution Prevention Plan (SWPPP)General Permit Part IV. Storm Water Pollution Prevention Plan (SWPPP)

Operator shall develop a SWPPP and submit a copy at the same time as the NOI form

Operator shall implement the SWPPP at the time construction activity commences

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

SWPPP (continued)SWPPP (continued)

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

The SWPPP must include maps(s) indicating:The SWPPP must include maps(s) indicating:

Areas of disturbance

Drainage patterns

Location of BMPs

Revegetation areas

Location of Impervious structures

Location of all surface waters

Location of 100 year floodplain

SWPPP (cont.)SWPPP (cont.)

Must include BMP description

Must preserve existing vegetation

None of temporary BMPs shall be removed until permanent vegetation and site stabilization has taken place

BMPs must minimize or prevent “significant sediment” from leaving the construction site

Notice of Termination (NOT) Form Notice of Termination (NOT) Form

Where a site has been finally stabilized the operator of a site shall submit a Notice of Termination to DEQ

“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

Storm Water ComplianceStorm Water Compliance

DEQ expects all permit holders to be in compliance with the provisions of the General Permit and the site specific SWPPP

DEQ will conduct inspections

DEQ will issue fines for non-compliance

Fines for non-complianceFines for non-compliance

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.

Fines for non-complianceFines for non-compliance

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.

Module 1 ReviewModule 1 Review

BMPs are required at construction sites larger than 1 acre

MDT has prepared a new BMP Manual

DEQ Requires a permit for each construction project

A site-specific SWPPP must be developed and implemented

BMPs must be maintained until the site is stable
