EPA Signals Clear Change Away from Enforcement and Toward Compliance

Through what may be EPA’s clearest statement of its change in direction under the Trump administration, the Office of Enforcement and Compliance Assurance recently announced its intention to transition the 20-year-old National Enforcement Initiatives program to the National Compliance Initiatives program. Through this less than subtle change, EPA is making clear its intent to move away from enforcement in favor of compliance and to encourage states to take on more responsibility. 

Handy Ohio & Federal Hazardous Waste Rules (RCRA) Regulations Cross-Reference

For those of you who utilize both Ohio and federal hazardous waste rules, Ohio EPA provides a useful cross-reference (or crosswalk) between Ohio and federal hazardous waste rules.  The hazardous waste crosswalk table is a numerical list of currently effective Ohio hazardous waste management rules, their title, effective date and an approximation of which 40 CFR provision they address. The list is not an equivalence document but can be used as a map to Ohio’s rules if you are more familiar with the federal RCRA rule-numbering system. Most states have a similar document, if you know where to look.

Vapor Intrusion Fundamentals 43 – EPA’s VI Attenuation Database

In 2012, EPA released a report titled, EPA’s Vapor Intrusion Database: Evaluation and Characterization of Attenuation Factors for Chlorinated Volatile Organic Compounds and Residential Buildings”. The information in the database was critical to EPA’s derivation of soil-gas and groundwater Vapor Intrusion Screening Levels (VISLs). To learn more about what the database does and doesn’t tell us, read on….

Ohio Abandoned Gas Stations Program Grant Updates

The Ohio Development Services Agency (ODSA) just announced some updates to their Abandoned Gas Station Cleanup Grant. This program provides up to $100,000 for assessment and up to $500,000 for cleanup of underground storage tank (UST) sites that have no viable responsible party. Applications can be made by local government entities, who may apply for their own properties or on behalf of other landowners. Although a petroleum component is required by the program, funds can also be used for hazardous substance investigations and cleanup (such as drycleaners). With the new changes, applicants may request up to $250,000 for a combined Assessment/Corrective Action in a single grant application. This is a tremendous opportunity for communities struggling with blighted service stations, or developers pursuing well-positioned properties with environmental concerns. Cox-Colvin has helped clients obtain these funds for property redevelopment that was not economically viable otherwise. Contact us if you have properties that may qualify, and we can assist you in securing these funds.

Vapor Intrusion Training Opportunity

In cooperation with the American Institute of Professional Geologists (AIPG), Ohio Section, Cox-Colvin and others will be offering a 2-day course on vapor intrusion on October 10 & 11, 2018 in Delaware, Ohio. This course is designed to help project managers who are making decisions about the risk of vapor intrusion, and field personnel, who will be collecting vapor-intrusion samples. CEU credits will be available.

The course will include the following topics:

  • History of Solvent Use
  • Conceptual Site Model
  • Regulatory Framework
  • Soil Assessment/Petroleum Hydrocarbons
  • Groundwater Assessment & Vapor Intrusion Screening Levels (VISLs)
  • Soil-Gas Interpretation
  • TCE/Real time Monitoring
  • Response Action Levels (RALs)
  • Indoor Air Collection & Measurement
  • TCE Risk Decision Matric
  • Laboratory Methods
  • Indoor & Ambient Air Interpretation
  • Vapor Mitigation & Long Term Monitoring
  • Subslab Depressurization Systems
  • Barrier Systems
