Please see attached Request for Proposal (rfp) for NMOC sampling and reporting at the Casper Solid

Waste Facility. I understand from our WDEQ Air Quality Division compliance officer, Chris Hanify, that

Casper needs to conduct NMOC sampling at both our closed Balefill and our active operating lined

landfill, Casper Regional Landfill (CRL). The city of Casper will be awarding a construction project later

this month to modify the closed Balefill’s passive gas system to an active GCCS that includes an enclosed

flare. The NMOC sampling work plan will need to be coordinated with our CQA consultant, Bill Hensley

and our City Engineer, Jason Knopp because the sampling must be done so the cap is NOT penetrated.

Please email me by Monday April 13, 2015 if your company plans to submit a proposal for conducting

the NMOC sampling and reporting for the Casper Solid Waste Facility by the due date of April 27, 2015

at noon. Below is a summary of the wastes received at our facility in the past 10 years. Also, attached

are documents related to our existing gas vents at the closed Balefill and an example contract.

If you have any questions about the rfp, please don’t hesitate to email the questions to me. I will

provide a written email response to all.

Summary of waste received at the Casper Solid Waste Facility:

2004 – 118,226.85 tons accepted at the closed balefill




2008 – 139,070.02 tons accepted at the Solid Waste Facility (both the closed balefill and the new Casper

Regional Landfill [CRL]). Waste received at the CRL began October 27, 2008.

2009 – 109,233.04 tons accepted at the Solid Waste Facility (both the closed balefill and the new Casper

Regional Landfill [CRL]). Closed balefill stopped receiving waste in Spring of 2009.
