4 average daily flow over the seven day driest period occurring once in a ten year period is less than twice the maximum amount of sewage discharge. One possible engineering solution to the problem with the existing point of discharge would be to redirect the treated sewage discharge so that it flows directly to Stoney Creek. Stoney Creek passes under Hwy 70, approximately 1800 feet east of Carden's Mobile Home Park. A pumping station could be installed at Carden's to pump the discharge from the new package facility to Stoney Creek via 1800 feet of 2 inch or 3 inch force main laid in the right of way (preferably in the roadway shoulder) of Hwy 70. The cost of adding the pumping station and force main would be in the $20, 000 to $30, 000 range. Arthur Mouberry, the head of the regional section of DEM, has indicated that DEM considers the flow in Stoney Creek to be insufficient for the proposed (and permitted) quantity of discharge from Carden's if the facility were presently being permitted for the first time. However, Stoney Creek is the theoretic destination of the discharge flow as the system and permit now exist (the existing NPDES permits states that the point of discharge is an "unnamed" tributary of Stoney Creek) . The position that DEM will ultimately take regarding the process of changing the point of discharge for Carden's is not clear at this time. Arthur Mouberry has indicated that DEM's present position would be that Carden's will not be forced to relocate the discharge point at this time. Carden's must, by agreement with DEM, have the package plant in operation by April 30, 1990, or DEM will begin assessing additional fines. At the time the package plant begins operating, it will be operating under a DEM "Special Order of Consent" (SOC) . The SOC will include requirements for the treatment facility to be monitored more closely than is usual for facilities not operating under an SOC. The Carden treatment facility's discharge quality requirements will have to be met if the facility is to avoid addition enforcement action by DEM. The additional enforcement action could include the loss of the discharge permit. There will be a public hearing within the process for the issuance of the SOC where the County and the neighborhood residents will have an opportunity to have input to DEM. It is possible, but not likely, that DEM will force Carden's to change its point of discharge as a result of the SOC hearing. In the event that the SOC hearing process does not cause DEM to order the change of Carden's discharge point, the next opportunity (following DEM's normal procedure for modifying or revoking the NPDES discharge permits) to change the point of discharge will be in the permit renewal process. Tim Donnelly, Arthur Mouberrry's deputy at the DEM regional office, indicated earlier this year that DEM would be willing to take a hard look at Carden's
