MINNEAPOLIS, MN 55441 612/559-1423 FAX: 612/559-2202 MEMORANDUM TO: STEVEN ROHLF - CITY OF ELK RIVER FROM: JOHN LICHTER - B.A. LIESCH ASSOCIATES, INC. DATE: DECEMBER 20,1993 RE: RENEWAL OF UNITED POWER ASSOCIATION CONDITIONAL USE PERMIT Based on our recent telephone conversation, I have taken a look at several issues with regard the Conditional Use Permit renewal request forwarded by United Power Association (UP A). The attached table indicates the impact of the new waste combustor rules on UPA. The regulated items are shown on the right hand column, the second column indicates the old standards for Class A incinerators which were taken from the State Register. The new standards shown are in the third column which also came from the Minnesota State Register. Federal guidelines for large municipal waste combustors are shown in the last column. These were taken from the Federal Register of February 11, 1991. Significant changes in emission standards include a drop in the carbon monoxide standards from 400 parts per million to 200 parts per .million, opacity from 20% to 10%, the addition of a mercury standard of 30 micrograms per dry standard cubic meter or 85% removal and lowering of acid gas emissions on a parts per million basis. Comprehensive emissions testing has been accomplished by UP A on five separate occasions, in November 1989, March and May of 1990, August of 1991, and in November of 1992. Another round of testing is scheduled for early 1994. At the completion of that test, all four seasons will have been tested by UPA. The second table enclosed illustrates RDF burned by UP A by month. The existing permit allows for 1,050 tons per day burned as a montWy average. In no case is this standard been exceeded. Our analysis of all of the emissions data collected by date by UP A indicates compliance with all applicable standards at this time and likely compliance with all new standards proposed by the State and the Federal Government.
