Technical Manual 1005 Appendix D has a procedure and equation for establishing the Total Hydrocarbons (THC) Worst-Case Outlet Allowable (WCOA) limit during an oxidizer Destruction and Removal Efficiency (DRE) stack test. In order to ensure accuracy and consistency, EMS has added our spreadsheet to our Website for use in performing this calculation when preparing a stack test report. The spreadsheet can be found under the "Consultant Services" tab on our Website (https://www.state.nj.us/dep/bts/consult.html).
