Page 1 of 1

• Choosing an Environmental Consultant

• Guidance Documents

  Connecticut Department of Energy & Environmental Protection Remediation Division guidance documents

• Covenant Not to Sue

  A Covenant Not to Sue is an agreement between DEEP and a prospective purchaser or owner of a polluted site that DEEP will not institute a claim against a party who has or will clean up that 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.

• Site Characterization Essentials

  Resources to help define the standard of care expected when characterizing a site under various clean-up programs in Connecticut.

• Green Remediation

  Greener cleanups can minimize the carbon footprint of site remediation by reducing the impact to energy, water and natural resources. The Department of Energy and Environmental Protection encourages the use of green and sustainable remediation practices in conducting site investigation and cleanup.

• General Guidance on Development of Former Agricultural Properties

  General guidance for site development projects on former agricultural land in which persistent pesticides (primarily dieldrin, DDT and breakdown products, chlordane, arsenic) remain in soil at concentrations that approach or exceed the Connecticut Remediation Standard Regulations

• Ecological Risk Assessment Guidance

  Ecological Risk Assessment is a structured scientific evaluation of the potential for harm to occur to ecological receptors as a result of exposure to some stressor, often an exposure to chemical contamination.

• Soil Preservation Guidance for VOCs

  The Department of Energy & Environmental Protection (DEEP) has issued a final guidance document describing soil sample collection and preservation techniques designed to minimize volatile organic compound losses due to volatilization and biodegradation.

• Well Receptor Guidance

  Guidance for persons who are required to investigate and remediate polluted or potentially polluted sites must consider the need to conduct a detailed water supply well receptor survey in order to assess whether an on-site groundwater pollution plume may, or can be reasonably expected to, adversely affect public or private water supply wells on and off-site.

• Trichloroethylene Developmental Risks

  As a result of the increased understanding of the developmental risks posed by TCE, the Connecticut Department of Public Health (CT DPH) and Department of Energy and Environmental Protection (DEEP) developed joint guidance in February 2015.

• Final SCGD

  The Site Characterization Guidance Document describes DEEP's recommendations for the investigation of properties and the suggested content of documentation that presents the facts and findings of site characterization by environmental professionals responsible for designing, conducting, and documenting site investigations and by any parties/persons required by law to conduct an investigation of a property in accordance with prevailing standards and guidelines.

• Guidance for Utility Company Excavation

  Department of Energy & Environmental Protection recommendations to be followed by utilities that encounter contaminated soil during repair or construction activities.

• Analytical Methods for Petroleum Releases

  The Extractable Total Petroleum Hydrocarbons (ETPH), Extractable Petroleum Hydrocarbons (EPH), and Volatile Petroleum Hydrocarbons (VPH) are analytical methods that are commonly used in Connecticut to characterize petroleum releases.
