5 Colo. Code Regs. § 1002-71.12
BASIS AND PURPOSE
This rulemaking is intended to update the regulation to reflect point source- nonpoint source tradeoffs that have occurred in the Dillon Reservoir watershed and to combine all point source allocations of the Breckenridge Sanitation District to a single total phosphorus allocation. These changes include adding 40 pounds to the Copper Mtn. Consolidated Metro District's phosphorus allocation in the regulation as credit for the removal of nonpoint source septic systems in the Ten Mile Creek drainage. These changes will not result in an overall increase in the total phosphorus load to Dillon Reservoir because the increase in allowable point source load is offset by a two-fold reduction in nonpoint source load.
Consolidation of Breckenridge Sanitation District (BSD) Phosphorus Allocations- BSD is the only entity providing central sewer treatment service in the entire Blue River watershed upstream of Dillon Reservoir. BSD currently owns and operates seven wastewater treatment facilities listed in section 4.1.3 of the Control Regulation. Several of the BSD facilities have recently been combined into a single more efficient treatment plant.
BSD has been a leader in phosphorus removal nationwide through a combination of advanced treatment facilities and significant operational expertise. This rulemaking combines all total phosphorus allocations for treatment facilities located in the BSD service area into a single total phosphorus allocation to enable streamlined facility consolidation, flexibility in operation, and improved reporting to the Division. A single total phosphorus allocation also updates the Control Regulation to the current operations and permitting situation of the BSD. This request fits within the original pollution control "bubble concept" outlined in the phosphorus management plan for Dillon Reservoir and is wholly supported by the Summit Water Quality Committee.
