In addition,,40 CFR 122.23(c) provides that the <br /> Director of an NPDES discharge permit program may designate any animal feeding operation as a <br /> concentrated animal feeding operation (which has the effect of subjecting the operation to the <br /> NPDES permit program requirements) upon determining that it is a significant contributor of water <br /> pollution. In such cases, upon issuance of a permit, the terms of the permit apply and this <br /> management measure ceases to apply. <br /> http://vv-w"W.epa.gov/owow/nps/MMGI/Chapter2/ch2-2bl.html 2/6/2009 <br />
