COLORADO DEPARTMENT OFPUBLIC HEALTHAND ENVIRONMENT, Water Quality Control Division Rationale -Page 5. Permit No. COR- 010000 Ill. STORMWATER DISCHARGESASSOCIATED WITH INDUSTRIAL ACTIVITY (cont.) Transportation facilities which have vehicle maintenance, fueling, equipment cleaning or airport deicing, including: 40 Railroad transportation 41 Local and suburban transit and interurban highway passenger transportation 42 Motorfreight transportation and warehousing (except 4221, 4222, 4225) 43 U.S. Postal Facilities* 44 Water transportation 45 Air transportation (facilities that use less than 1000 gallons of deicers) annually, and /or that have annual fuel sales of less than one million gallons /year) 5171 Petroleum bulk stations & terminals *The Division currently does not have permitting authority over federal facilities. Should this change during the life of this permit, facilities under SIC Code 43 may be covered by this permit. Although the Office of Management and Budget's North American Industry Classification System is intended to replace the 1987 Standard Industrial Classification Code, Colorado has decided to continue using the 1987 SIC code system as the primary classification system under Colorado's stormwater permits because the slorinwater regulations (Colorado Discharge Permit Regulations, Reg. 61) refer to these codes and because this code system identifies facilities adequately. EPA is implementing the same policy in its Multi- Sector General Permit. For any facilities that do not require coverage under the stormwater regulations, but still wish to be covered under this general permit, the Division reserves the right to certify them tinder this permit. The Division also reserves the right to include under this general permit any specific facility not otherwise covered. This determination would be based on the reasonable potential of a specific industrial discharger to contribute to a violation of a water quality standard, or to be a significant contributor a ollutanis to state waters. IV APPLICATIONANO CERTIFICATION Certification under the permit requires submittal of an application. Upon receipt of all required information, the Division may allow or disallow coverage under the general permit. See Part LA.3 of the permit for an outline of the applicable time frames. At least thirty days prior to the anticipated date of discharge, the owner (or operator when the owner does not operate the facility) of thefircility shall submit an application as provided by the Division. (Note - Under the Federal regulations, this is referred to as a Notice of Intent, or NOI. For internal consistency with its current program, the Division will continue to use the term "application.') Refer to Part LA.2. b of the permit for a description of what must be included in an application for coverage under this permit. If this general permit is applicable, then a certification will be developed and the applicant will be certified tinder this general permit. � : TERMS AND CONDITIONS OF PERMIT A. StorimvaterManairement Plans (SWMPs): The purpose of a SWMP is to identify possible pollutant sources to stormwater and to set out best management practices that, when implemented, will reduce or eliminate any possible water quality impacts. A SWMP shall be developed for each facility covered by this permit. SWMPs shall include BMPs that are selected, installed, implemented and maintained in accordance with good engineering practices to minimize pollutants in the discharge so that the discharge will not cause or contribute to an excursion above any applicable water quality standards. (The plan need not be completed by a registered engineer.) The Division has a guidance document available on preparing a SWMP. The document is on the Division 's websile at www.cdphe.state.co. us 1wg1PermitsUnit.
