EPA Broadens Definition of 'Remote' Sites for Stationary Engine Air Compliance
A change in the definition of EPA's NESHAP Subpart ZZZZ air compliance regulations could bring good news for companies with RICE.
A change in the definition of what a “remote” site is in EPA’s NESHAP Subpart ZZZZ air compliance regulations could bring good news for companies with stationary reciprocating internal combustion engines (RICE). Stationary RICE engines are typically used at natural gas compressor stations, for other uses in the oil and gas industry and for landfills.
The modified definition, which went into effect January 30, 2016, makes a change to what is considered to be “remote.” If a company’s RICE is remote, the engine will be exempt from Subpart ZZZZ requirements for initial compliance testing.
According to the new rule, a remote engine is now considered to be:
Frequently Asked Questions
Q: What are stationary RICE engines and which industries use them?
A: Stationary reciprocating internal combustion engines (RICE) are fixed engines commonly used in natural gas compressor stations, oil and gas production facilities, and landfill operations. These engines are subject to EPA NESHAP Subpart ZZZZ air emissions regulations, though exemptions may apply to “remote” installations.
Q: How did the January 30, 2016 remote site definition change benefit RICE operators?
A: The 2016 EPA rule modification expanded the definition of “remote” sites, allowing more facilities to qualify for an exemption from initial NESHAP Subpart ZZZZ compliance testing requirements. This change potentially reduced testing costs and compliance burden for facilities in qualifying locations.
Q: Do all RICE engines at remote sites require compliance testing?
A: No. If a RICE engine qualifies as “remote” under the modified EPA definition effective January 30, 2016, the engine is exempt from initial NESHAP Subpart ZZZZ compliance testing requirements. However, iSi Environmental recommends verifying your specific site location and equipment configuration against EPA’s current remote site criteria.
Q: What happens if my facility’s RICE engine does not qualify as remote?
A: Non-remote RICE engines remain subject to full NESHAP Subpart ZZZZ compliance testing and emissions monitoring requirements. iSi Environmental can conduct initial compliance testing and establish ongoing monitoring protocols to ensure your facility meets EPA air permitting obligations.
