40 CFR 63 Subpart ZZZZ covers all stationary reciprocating internal combustion engines at both major and area sources of Hazardous Air Pollutants (HAPs).

 

Notification and compliance requirements vary depending on several factors, including:

  • whether a source is a Major or Area Source for HAPs
  • whether the RICE in question is a compression or spark ignition engine
  • the horsepower of the engine
  • the engine’s displacement
  • whether the RICE is continuous use, limited use, or emergency use

Some stationary RICE are subject to this rule, but do not have any emissions limitations or notification requirements associated with the rule.  Those RICE that do not have any emissions limitations or notification requirements are:

  • Existing emergency residential, commercial, & institutional at area sources
  • Existing limited use > 500 HP at major source
  • Existing emergency > 500 HP at major source
  • Existing spark ignition 4SLB > 500 HP at major source
  • Existing spark ignition 2SLB > 500 HP at major source
  • Existing landfill digester gas > 500 HP at major source
  • New reconstructed or constructed on or after 6/12/06 and before 1/1/08 that is non-emergency spark ignition > 250 HP at major source

Please note that these classes of engines will most likely have some requirements, such as routine maintenance, under this rule.  See the resources below to determine your facility's exact requirements.  All other stationary RICE are subject to emissions limitations and notification requirements under this rule or under the New Source Performance Standards (NSPS) Subpart IIII or Subpart JJJJ

To assist operators of sources with Reciprocating Internal Combustion Engines in determining their compliance and reporting requirements, the EPA has developed a spreadsheet matrix to identify which compliance and reporting category each RICE fits in.
