• Licensed Environmental Professional (LEP) Verification Audit Program

  The purpose of the Licensed Environmental Professional (LEP) Verification Audit Program is to ensure that the opinions ("verifications") of the LEP are based on an appropriate understanding of the environmental conditions of the site and that the verification is in compliance with all applicable statutes and regulations, including the Remediation Standard Regulations (RSRs).

• Siting Clean Energy on Brownfields

  Renewable energy, such as wind and solar, can be sited on land that has been or is perceived to be polluted and is now underused. These properties, called brownfields, may be particularly attractive because these types of renewable energy installations may require large sites, and brownfields are usually large sites located in areas with the existing infrastructure needed to support development.

  Information regarding contaminated sites or potentially contaminated sites in Connecticut.

• Superfund Programs

• Environmental Use Restrictions

  An Environmental Use Restriction (EUR) is used to minimize the risk of human exposure to pollutants and hazards to the environment by preventing specific uses or activities at a property or a portion of a property.

• Quality Assurance and Quality Control

  An evaluation of the quality of the analytical data in relation to its intended use is important in order for the environmental professional to make decisions which are supported by data of known and sufficient quality.

• Technical Impracticability Variance

  A Technical Impracticability Variance is a remedial option provided under the Connecticut Remediation Standard Regulations (RSRs) when non-aqueous phase liquids cannot be contained or removed in accordance with Section 22a-133k-2(g) of the RSRs, remediation to the extent technically practicable has reduced the concentration of pollutants in groundwater to steady-state concentrations, or as otherwise specified in EPA guidance.

• Introduction to Per- and Polyfluoroalkyl Substances (PFAS)

  Per- and polyfluorinated alkyl substances are a group of over 4,000 manmade chemicals, collectively referred to as PFAS, that have recently entered the national spotlight as emerging contaminants with serious adverse impacts on human health, even at low concentrations in the parts per trillion range.

• Contaminants of Emerging Concern

  An emerging contaminant is a chemical or material characterized by a perceived, potential, or real threat to human health or the environment or by a lack of published health standards. General information on emerging contaminants, as well as perchlorate, nanomaterials, and pharmaceuticals and personal care products.

• Engineered Control Variances

  An Engineered Control is a permanent physical structure designed to safely isolate pollutants which would otherwise not comply with the self-implementing remedial options allowed in the Connecticut Remediation Standard Regulations (RSRs).
