Section 5 CCR 1002-33.35 - STATEMENT OF BASIS, SPECIFIC STATUTORY AUTHORITY AND PURPOSE, MARCH, 2002 RULEMAKING

The provisions of sections 25-8-202(1)(a), (b) and (2); 25-8-203; 25-8-204; and 25-8-402, C.R.S., provide the specific statutory authority for adoption of the attached regulatory amendments. The Commission also adopted, in compliance with section 24-4-103(4), C.R.S., the following statement of basis and purpose.

BASIS AND PURPOSE

In this hearing the Commission adopted a proposal by The Pittsburg and Midway Coal Mining Co. to modify the water supply standards for Yampa River segment 13c to conform with the revisions to the Basic Standards and Methodologies for Surface Water (Regulation #31) at 31.11(6) adopted in 2000.

P&M requested modification to the water supply standards of iron, sulfate and manganese, for Yampa River segment 13c. P&M has a permit to discharge to this segment and waiting to incorporate these changes until the next basin-wide review would result in a hardship.

By this action, Table 33.6(2) Abbreviations is modified to include the "WS(dis)" notation and the explanation from 31.11(6). In addition, the notation for Yampa River segment 13c for iron, sulfate and manganese is changed from numerical values to "WS(dis)".
