DEEP Concurrence with ITRC Technical Guidance Documents

ITRC logo
The Interstate Technology and Regulatory Council (ITRC) is a public-private coalition with members from all 50 states and the District of Columbia.  It produces documents and training to broaden and deepen technical knowledge and expedite quality regulatory decision-making while protecting human health and the environment.  Because ITRC guidance are written for a national audience, the guidance cannot reflect the individuality of state environmental rules.  DEEP recommends users carefully consider how the guidance interrelate to Connecticut’s laws and regulations.  DEEP has prepared Concurrence documents for certain ITRC guidance to assist environmental practitioners in applying technical advances described by ITRC guidance documents to the remediation of Connecticut sites in conformance with the Remediation Standard Regulations.
