Questions & Answers

Page 3 of 3 5/21/2026

1. Question: The Background and General Scope of Work of the solicitation require the contractor to provide a Certified Industrial Hygienist (CIH). A CIH credential is not required by EPA's voluntary guidelines for methamphetamine remediation, NIOSH Method 9111, or any applicable South Dakota state regulation governing this type of work. This requirement appears more restrictive than necessary to satisfy the Government's minimum needs and may artificially limit competition within the already-restricted ISBEE bidder pool. Please provide the technical basis for the CIH requirement.

Response: The Government acknowledges that EPA’s voluntary cleanup guidelines and NIOSH Method 9111 do not specifically require a CIH credential. However, the Bureau of Indian Affairs has determined, based on internal environmental health standards and previous methamphetamine remediation projects, that a Certified Industrial Hygienist provides the level of technical competence necessary to protect human health, ensure regulatory compliance, and verify clearance for re-occupancy. This requirement reflects the Government’s minimum needs for professional oversight, quality assurance, and risk management. Therefore, the CIH requirement will remain as stated.
