ESSI is pleased to announce that we have reduced  one of our customer’s, on the Ohio River, sampling frequencies for their National Pollutant Discharge Elimination Permit (NPDES).  The sampling frequency in the prior permit was two times a month and the new permit reflects a sampling frequency of one time a month.  The sampling parameters were not expanded.  This will save the operator time and expenses for sampling and reporting.  The operator retained ESSI to complete the permit renewal application and review the draft permit.  ESSI’s draft permit comments led to the sampling frequency reduction.  For more information regarding our waste water (NPDES) permitting and sampling services give a call: (812) 402-3774 or email: cjz@essi-inc.com our office (www.essi-inc.com).
