• Determining frequency of coordination activities
  

  The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). Are stationary sources responsible for determining if coordination activities should occur more often than annually? Ultimate responsibility…

• Who Must Develop an Emergency Response Program?

  The risk management program regulations require the owner or operator of a covered stationary source to develop and implement an emergency response program as described in 40 CFR §68.95, which must include an emergency response plan, emergency response equipment procedures, employee training, and procedures to ensure the program is up-to-date…

• What is a site assessment and what is the difference between a site assessment and a site investigation?

  The first step of the site assessment process is known as a preliminary assessment (PA). This assessment gathers historical and other readily available information on site conditions and surroundings to evaluate whether the site poses a potential threat to human health and the environment and/or whether further investigation is needed…

• Why hasn’t the Norwood Landfill Site been identified as a Superfund Site? Two nearby landfills, Folcroft and Clearview, which were established and in use at the same time as Norwood Landfill and Dump have both been designated as Superfund sites.

  EPA is still conducting its investigation of the Norwood Landfill Site to determine if it should be placed on the National Priorities List (NPL), or Superfund List. Thus far, the data collected has not demonstrated that the site warrants placement on the NPL. Both the Folcroft and Clearview Landfills went…

• What sources make up the Tier 1 categories used in the emissions trends?

  Tier 1 categories are assigned by source classification codes (SCCs) that are the most specific processes available in the NEI. The latest SCC list with the Tier 1 assignments can be downloaded from the EPA SCC website in Comma Separate Values (CSV) format.

• What is the cause of the large decrease in electric utility emissions, particularly sulfur dioxide, starting in 1995?

  SO2 emissions reductions from utilities during this time are primarily attributed to the impacts of the acid rain program. As described on EPA’s Acid Rain Program web page, Phase 1 of this program began in 1995 and affected 263 units at 110 most coal-burning electric utility plants in 21 eastern…

• Why did EPA wait so long to begin its investigation of the Norwood Landfill and Old Norwood Dump?

  In the months leading up to the preliminary assessment, EPA gathered information on the property to determine whether a site investigation under the Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) was warranted. EPA determined to proceed with an investigation and EPA began procuring contractor services to conduct the preliminary…

• What is the key question EPA tries to answer through a site investigation?
  
  

  Findings of the site investigation determine what hazardous substances may be present, whether they may be released to the environment, and any potential threat to human health. Information about the site that is collected in the preliminary assessment and site investigation phase helps EPA to evaluate the risks posed by…

• Remote coordination with local authorities
  

  The Risk Management Program regulations require owners and operators of stationary sources to coordinate their response needs annually, or more frequently if necessary, with local emergency planning and response organizations (40 CFR §68.93(a)). If a stationary source is in a remote location and in-person annual coordination is deemed impractical, can…

• Emergency Response Coordination Activities Effective Date

  The RMP Amendments finalized on January 13, 2017 included a requirement for owners or operators of a stationary source to engage in emergency response coordination activities (40 CFR §68.93). The regulatory text in 40 CFR §68.10(b) states that compliance with these activities must be completed by March 14, 2018. Because…

• Why do mobile source NOx emissions jump higher between 2001 and 2002 on the emissions trends?

  The emissions model used for mobile sources changed from MOBILE6.2 to MOVES 2010 in December 2009. This change included a notable increase in NOx emissions. The EPA adjusted data back to 2002 to reflect the change in models. The higher emissions in 2002 are because of this method change and…

• Why do the PM2.5 emissions for the electric utilities source category jump up between 1998 and 1999?

  The estimation method for PM emissions from fuel combustion sources was enhanced beginning with the 1999 National Emissions Inventory. Prior to 1999, the emissions measurement data methodology only included the filterable portion (which means the solid particle matter at elevated stack temperatures). Beginning with the 1999 NEI, both the filterable…

• Types of Information Relevant for Response Planning

  The Risk Management Program emergency response coordination activities require the owner and operator of a stationary source to provide to the local emergency planning and response organizations: the stationary source’s emergency response plan if one exists; emergency action plan; updated emergency contact information; and any other information that local emergency…

• Are exercises required as a part of the emergency response program requirements under 40 CFR Part 68, Subpart E?

  Yes. At least once each calendar year, the owner or operator of a stationary source with any Program 2 or Program 3 process must conduct an exercise of the stationary source's emergency response notification mechanisms per 40 CFR 68.90(b)(3) or 68.95(a)(1)(i), as appropriate, before December 19, 2024, and annually thereafter…
