Dear Mr. Walls:
William G. Ross Jr., Secretary
Gregory J. Thorpe, Ph.D.
Acting Director
Division of Water Quality
Enclosed you will find a copy of the Pretreatment Compliance Inspection Report for the inspection
conducted on May 2, 2002. The report indicates that Troy WWTP continues to meet the pretreatment requirements
as outlined in 15A NCAC 2H .0904 (b) for Modified Pretreatment Programs. You are commended for your
continued success in maintaining your program.
As a reminder, every five years the IWS and HWA need to be updated. They are due at the Pretreatment
Unit in Raleigh by the month of October 2003. Enclosed with this report is the schedule frequency and sampling
plan copied from the N.C. Pretreatment Comprehensive Guide for Modified Pretreatment Programs. The STMP for
Modified PT programs was originally designed with 4 consecutive days of monitoring at the WWTP influent and
effluent. However, the Division is now strongly recommending one influent and effluent sample each quarter for 4
quarters. The Division presents a one -day HWA training session to instruct POTW pretreatment staff and
consultants in developing an HWA. The PT Unit holds them approximately once every two months, usually
alternating between the eastern half and western half of the state. Please contact the PT Unit if you wish to attend
an HWA workshop.
The report is self-explanatory and contains observations and recommendations. If you or your staff have
any questions or require clarification, please do not hesitate to contact me at [phone].
