The EPA continues to develop the performance of its interactive Benzene Fenceline Monitoring Dashboard and its Enforcement and Compliance Historical past (ECHO) web site. These instruments present data on environmental compliance and enforcement for communities throughout the USA.
“By means of improved transparency, superior applied sciences and group participation, these instruments empower the general public to assist EPA guarantee compliance nationwide and shield public well being and the atmosphere,” says an EPA information launch.
Benzene fenceline monitoring
The Nationwide Emissions Requirements for Hazardous Air Pollution (NESHAP) for petroleum refineries require steady fenceline monitoring of the poisonous air pollutant benzene alongside the perimeter of refinery amenities. Fenceline monitoring is designed to observe undetected leaks, also referred to as “fugitive emissions,” that are thought of to be a major supply of emissions.
Preliminary monitoring instruments had been passive samplers that seemed like small tubes that contained carbon sorbent supplies. They had been hung round facility fencelines uncorked. Then, every week or 2 later, they had been recapped and despatched in for evaluation. The issue with these samplers was that the information supplied was not instantaneous and wind course was not factored.
Then, the EPA developed a low-cost SPod, an open-source-designed, solar-powered “drop in place” sensor system that supplied real-time fenceline information.
The actual-time information responds to calls for from environmental and group teams.
“Individuals need extra information on what pollution they’re uncovered to each day as monitoring expertise will get higher, King & Spalding LLP accomplice Craig Stanfield stated,” in keeping with Bloomberg Legislation.
The supply of fenceline and group monitoring information is on the coronary heart of a number of lawsuits throughout the nation. Courts are asking state and native companies to dig deeper for extra information to find out emissions sources and legal responsibility for alleged hurt from these emissions.
In February 2022, the EPA Workplace of Inspector Common (OIG) introduced it will start fieldwork to audit the EPA’s benzene fenceline monitoring program for petroleum refineries. The target of the investigation “is to find out to what extent oversight of the benzene fenceline monitoring program by the EPA and delegated state and native companies assures that refineries take corrective motion and decrease benzene, as required, when measured benzene concentrations exceed the motion stage.”
Petroleum refineries are required to observe benzene concentrations and report the outcomes to the EPA on a quarterly foundation. The brand new EPA Benzene Fenceline Monitoring Dashboard device offers the outcomes of these reviews to the general public.
“The Dashboard improves public entry to program information regarding benzene emissions alongside refinery fencelines and permits for a extra detailed evaluation of that information,” provides the EPA’s information launch. “Public entry to this data advances public transparency and environmental justice.”

ECHO
The ECHO device offers built-in searches of EPA and state information for greater than 800,000 regulated amenities. ECHO focuses on inspection, violation, and enforcement information for the Clear Air Act (CAA), Clear Water Act (CWA), and Useful resource Conservation and Restoration Act (RCRA) and likewise contains Secure Ingesting Water Act (SDWA) and Toxics Launch Stock (TRI) information.
The brand new performance integrates environmental justice (EJ) metrics into the ECHO options, permitting customers to:
- Seek for amenities in areas with doable EJ considerations.
- Examine air pollution sources in areas with doable EJ considerations.
- Look at and create EJ enforcement-related maps.
- Analyze tendencies in compliance and enforcement EJ information.
