3. Regional Wastewater SDCs For Atl Existing Development <br /> Regional Wastewater SDCs For Existing Single-Family Dwellings and <br /> Duplex Development <br /> For existing single-family dwellings, the regional wastewater SDC collected <br /> is equal to the rate for one EDU. For all duplex development, the regional <br /> wastewater SDC collected is equal to two times the rate for one EDU. <br /> Regional Wastewater SDCs For All Other Existing Development with <br /> Annual Average Daily Flow less than 100,000 Gallons <br /> For administrative convenience, rather than verifying by physical inspection <br /> the number of plumbing fixture units in an existing development that is <br /> connecting to the wastewater system for the first time, the regional <br /> wastewater SDC collected shall be determined by using the average historic <br /> winter water consumption for the existing development. The existing <br /> development's historic consumption is calculated by averaging the actual <br /> winter water consumption, in gallons, for the preceding months of December <br /> through April, dividing the resulting number by 1,000, and multiplying by the <br /> rate for historic consumption. The rate for historic consumption (per 1,000 <br /> gallons) is based on an assumed typical single-family dwelling average <br /> winter water consumption of 6,000 gallons per month. <br /> Regional Wastewater SDCs For All Other Existing Development with <br /> Annual Average Daily Flow Equal to or Greater than 10,0,000 Gallons <br /> For existing development with measured annual average daily flow equal to <br /> or greater than 100,000 gallons of water discharged, the regional <br /> wastewater SDC collected is equal to the total amount of water being <br /> discharged per day, divided by the EDU standard 200 gallons per day, <br /> multiplied by the rate for one EDU. The regional wastewater SDC charge <br /> will be based on the greater of calculations using either the City <br /> methodologies or the current MWMC Equalization Fee charge. <br /> 4. Regional Wastewater Administrative Charge <br /> A further adjustment to the regional wastewater SDC is the addition of <br /> administrative costs. MWMC will incur staff costs for the updating and processing <br /> of the charge. These costs would be applied on a per connection basis. The <br /> administrative cost per permit is calculated, based on estimated administrative <br /> costs and future connections. The Regional Wastewater Administrative Charge per <br /> permit is~applied to the total SDC fees after all other charges and credits have been <br /> applied. <br /> <br /> Exhibit B to Administrative Order No. 58-97-02-F-1 <br /> <br />
