Issues & Trends: DNR’s Alternative RCL Calculator for cPAHs
Today at noon, please join the RR Program for a teleconference discussion of the RCL spreadsheet and a substitute method of calculating alternative non-industrial direct-contact residual contaminant levels (RCLs) for select carcinogenic polycyclic aromatic hydrocarbons (cPAHs).
Waste management specialist Paul Grittner and hydrogeologist David Swimm, both with the RR Program, will discuss the modified soil RCL spreadsheet which can be used to attain compliance when the applicable cPAH direct contact RCLs in NR 720 is not practicable. The spreadsheet changes how non-industrial direct contact RCLs for seven cPAHs are assessed. The spreadsheet evaluates cPAH compounds on a cumulative basis only, rather than on an individual compound basis and a cumulative basis.
The modified calculator and two related guidance documents can be found on the Resources for Environmental Professionals web page.
This approach is allowed under NR 722, but Program pre-approval is required prior to implementation. Paul and David’s presentation will focus on the process recommended for assessing PAH data using the modified soil RCL spreadsheet, as well as the DNR pre-approval process. The training session details are:
- Date: October 4, 2017
- Time: 12:00 - 1:00 p.m.
- Join by phone: 1-855-947-8255, passcode 6612745#
- Questions in advance or during the presentation can be sent to DNRRRComments@wisconsin.gov
No pre-registration is required. The presentation will be recorded and made available on Thursday on the RR Program’s Training Library.
