PART II Permit - Page 24 Permit No, COR -030000 11. CHANGES IN THIS GENERAL PERMIT (cont.) B, Atithorily ►rr Dis me -Oil cord Ga.y Consiniction This section has been added, to take into account a regulatory change. The federal Energy Policy Act of 2005 exempts nearly all oil and gas construction activities fi-otn federal requirements under the Clean Water Act's NPDES stormwater discharge permit program. In January 2006, the Colorado Water Quality Control Commission held a hearing to determine what effects, if any, the change in federal law would have upon Colorado's stormwater regulations. The Commission determined that oil and gas construction sites in Colorado that disturb one or more acres are still required to be covered under Colorado's stormwater permitting regulations (Colorado Discharge Permit System (CDPS) regulations (SCCR 1002-61)). In practice, oil and gas construction sites have the satire requirements under this permit as do other types of construction. However, this permit contains some references to the federal Clean Water Act; generally these references are not applicable to oil and gas construction sites to the extent that the references are limited by the federal EnergyPolicy Act of 2005, See Part LA, l (b) of the permit. C. Allilic flon Regtt_ir n tv The permit application requirements have changed slightly, including the addition of an email address, if available. See Part LA.4(b). The applicant must be either the owner and/or operator of the construction site. An operator at a construction site that is not covered by a certification held by an appropriate entity may be held liablefrrr operating without the necessary permit coverage. D. Terri Mi_ary Coive Part LA,S(d) of the previous permit (effective July 1, 2002) dealt with temporarily covering a facility under the general permit even if an individual permit is more appropriate. This permit section essentially duplicated the previous section (see Part LA. 5(c)), and so it has been deleted. E. Reassi =nates u 'Per snit Cavei ct e Procedures have been added to clam the requirements for the transfer of coverage ofs re(i to ror 'cans of a permitted site to a second parry. See Section VII1.1.3 of the rationale and Part LA.8 of'the permit. F. Individual Permit Criteria This section has been modified to include situations involving a Total Maximum Daily Load (TMDL).

Storanvater lticniaeerrte►t Plan (SWMP) The Stormwater Management Plan section has been divided into two parts: Stormwater Management Plan (SWMP) - General Requirements, which provides the basic framework and general requirements for the SWAP, and Stormwater Management Plan (SWMP) - Contents, which specifically identifies each item that must be addressed in the SWMP. See Parts LB and LC of the permit. H. Sl{lrl► water Management Plan (SWUP) - enera Req�rir entertts The SWMP General Requirements section has been modified to require that the SWMP be updated in accordance with Parts LD.S(c) and LD.S(d) of the permit (SWMP Review/Changes). This additional requirement ensures that the SWMP provisions reflect current site conditions. See Part 1B.2(c) of the permit.
