Rule Interpretation Memos (RIMs) for Waste Management Regulations
The TCEQ Waste Rule Interpretation Team existed from 1999-2003 to address questions regarding state and federal waste rules. All interpretations made by the Waste Rule Interpretation Team were documented in rule interpretation memos (RIMs).
Who developed RIMs?
The Waste Rule Interpretation Team consisted of representatives from the Environmental Law; Litigation; Policy and Regulations; Field Operations; Enforcement; Registration, Review & Reporting; Remediation; and Waste Permits divisions of the TCEQ.
Why were RIMs issued?
The RIMs documented agreements among various parts of the TCEQ regarding the interpretation of certain rules. The process helped ensure consistency in permitting, enforcement, and other areas affected by these rules.
