This document is intended to work with an NPDES permit to provide permittees guidance for total toxic organic testing, a requirement in the permit.
A. General
A complete TTO analysis involves testing for up to 5 fractions containing 111 compounds. However, the Pesticide Fraction and Dioxin need not be included in the TTO analysis unless specifically requested by the Department. The Department may also, on a case-by-case basis, add additional parameters to this TTO list.
B. Calculation of TTO Value
TTO test results are calculated by summing all quantifiable values greater than 0.01 milligrams per liter (mg/L) for the TTO compounds. In situations where the concentration of a compound is below the detection limit, it need not be included. However, the Department may reject an analysis as inconclusive and request follow-up monitoring if the detection limits are too high to provide reasonable assurance of compliance.
C. Reporting of Results
The TTO value calculated as set forth above is to be reported on the appropriate Discharge Monitoring Report (DMR) and a copy of the laboratory report showing the test results for each individual compound is to be attached to both the Department's and City's copy of the DMR.
