ICE Notification Requirements - NESHAP ZZZZ Modifications 10/2010
Here's a quick analysis of notification, reporting,and recordkeeping requirements in the 8/2010 revision to NESHAP Subpart ZZZZ for RICE (FR 51570 ff.). Rebecca passed along an e-mail reminder from WDEQ that some existing engines require initial notifications to the state and EPA by February 16, 2011. The message also noted that the effective date for applicable requirements is October 19, 2013.
63.6645(a)(2) requires notifications for all existing stationary RICE located at an area source of HAP emissions and existing major source RICE less than 500 HP (site rating), but (a)(5) exempts the following:
-- <100 hp
-- emergency RICE,
-- RICE not subject to any numerical emission standards.
According to Table 2d, these are the only area source SI engines that are subject to numerical emission standards (and so would require notifications):
-- non-emergency; non-black start; 4SRB/LB; >500 HP
According to Table 2c, these are the only major source SI engines that are subject to numerical emission standards (and so would require notifications):
-- non-emergency; non-black start; 4SRB/LB or 2SLB or any engine firing landfill or digester gas; >500 HP
Note that required notifications for CI engines should already have been submitted.
Here are some pertinent sections of the rule revision FR notice (with my highlights and notes).
SUMMARY: EPA is promulgating national emission standards for hazardous air pollutants for existing stationary spark ignition reciprocating internal combustion engines that either are located at area sources of hazardous air pollutant emissions or that have a site rating of less than or equal to 500 brake horsepower and are located at major sources of hazardous air pollutant emissions.
DATES: This final rule is effective on October 19, 2010.
F. What are the reporting and recordkeeping requirements?
The following sections describe the reporting and recordkeeping requirements that are required under this final rule.
Owners and operators of existing stationary emergency SI RICE that do not meet the requirements for nonemergency engines (meaning emergency engines?) are required to keep records of their hours of operation. Owners and operators of existing stationary emergency SI RICE must install a non-resettable hour meter on their engines to record the hours of operation of the engine.
Owners and operators of existing stationary SI RICE located at major sources that are subject to work practices and existing stationary SI RICE located at area sources that are subject to management practices are required to keep records that show that the work or management practices that are required are being met. These records must include, at a minimum: Oil and filter change dates and corresponding engine hours of operation (determined using hour meter, fuel consumption data, or other appropriate methods); inspection and replacement dates for spark plugs, hoses, and belts; and records of other emission-related repairs and maintenance performed.
In terms of reporting requirements, owners and operators of existing nonemergency stationary SI RICE greater than or equal to 100 HP and less than or equal to 500 HP located at major sources of HAP and existing nonemergency 4SLB and 4SRB stationary RICE greater than 500 HP located at area sources of HAP that operate more than 24 hours per calendar year must submit the notifications required in Table 8 of 40 CFR part 63, subpart ZZZZ, which lists the NESHAP General Provisions applicable to this rule. (40 CFR part 63, subpart A) These notifications include an initial notification, notification of performance test, and a notification of compliance for each stationary RICE which must comply with the specified emission limitations. Owners and operators of existing stationary nonemergency SI RICE greater than or equal to 100 HP and less than or equal to 500 HP located at major sources of HAP and existing stationary 4SLB and 4SRB nonemergency SI RICE greater than 500 HP located at area sources of HAP that operate more than 24 hours per calendar year must submit semiannual compliance reports.
Must submit all general rqmnts notifications--including initial notification--and semiannual compliance reports:
** SI, 100 ≤ hp ≤ 500, nonemergency, major source
** 4SLB/RB, ≤500 Hp, nonemergency, area source, operates >24 hr/yr
REVISED NOTIFICATION REGULATORY TEXT
63.6590(b)(3)
(3) The following stationary RICE do not have to meet the requirements of this subpart and of subpart A of this part, including initial notification requirements:
(i) Existing spark ignition 2 stroke lean burn (2SLB) stationary RICE with a site rating of more than 500 brake HP located at a major source of HAP emissions;
(ii) Existing spark ignition 4 stroke lean burn (4SLB) stationary RICE with a site rating of more than 500 brake HP located at a major source of HAP emissions;
(iii) Existing emergency stationary RICE with a site rating of more than 500 brake HP located at a major source of HAP emissions;

RICE NESHAP Final Rule
RICE NESHAP Final Rule (from Trinity Consultans March 2010 newsletter)
On February 17, 2010 EPA finalized portions of the National Emission Standards for Hazardous Air Pollutants for Reciprocating Internal Combustion Engines (RICE NESHAP). The rule will be incorporated into the already existing RICE standards located in 40 CFR Part 63, Subpart ZZZZ. The standards apply to only stationary RICE and were originally proposed on February 25, 2009. The proposed standards included provisions for RICE located at area sources of hazardous air pollutants (HAP) and RICE with a site rating of less than or equal to 500 brake horsepower (bhp) located at major sources of HAP. In addition, the proposal included standards for existing non-emergency compression ignition (CI) engines with a site rating of greater than 500 bhp at major sources and revised provisions related to Startup, Shutdown, and Malfunction (SSM) events for engines previously regulated under the rule.
The promulgation of these regulations means that many previously unregulated engines, including those designated for emergency use, will be subject to federal regulation, including emission standards, control requirements, or management practices.
Following public comment on the proposed rule, the EPA made a number of significant changes to the promulgated rule. Following is a summary of those changes:
- The EPA did not finalize the proposed provisions for spark ignition (SI) engines. Although the original proposal included SI engines at area sources as well as those less than or equal to 500 bhp located at major sources, the EPA has determined that additional data is needed prior to finalizing rules for these sources. The EPA expects to finalize the rules associated with SI engines by August 10, 2010. (final rule to include SI RICE published 8/20/2010, KMM)
- Existing emergency engines at area sources that are located at residential, commercial, or institutional facilities are not subject to the final rule. A definition for residential/commercial/institutional facility has been included in the final rule.
- Several numerical standards originally proposed for some categories of engines have been replaced with management practices.
- The EPA revised the numerical emission limit for several engine categories based on a re-evaluation of the MACT floor.
- The EPA added an option to the management practices to use an oil change analysis program to extend the oil change frequencies listed in the final rule. Details of the analysis program are included in the final rule.
- The EPA eliminated the numerical standards originally proposed during periods of SSM, instead promulgating operational standards that apply during startup. Additionally, the standards that apply during normal operation now also apply during periods of shutdown and malfunction.
- The EPA included an additional requirement to reduce metallic HAP emissions for certain engine categories, including existing non-emergency CI greater than 300 bhp. A closed crankcase ventilation system or open crankcase filtration system must be installed on these engines, if the engine is not already equipped with a closed crankcase ventilation system.
- An exclusion from the numerical emission limits has been included for existing non-emergency CI RICE greater than 300 bhp located at area sources in Alaska that are not accessible by the Federal Aid Highway System. These engines are required to meet the management practices listed for non-emergency CI RICE less than or equal to 300 bhp.
- A definition for emergency stationary RICE has been added to the final rule. The majority of the requirements that apply to emergency stationary RICE listed in §63.6640(f) are identical to the proposed rule; however, the final rule allows an emergency unit to participate in an emergency demand response program as a part of a financial arrangement with another entity for up to 15 hours per year. Additional requirements also apply to units participating in emergency demand response programs. The detailed requirements are listed in §63.6640(f) of the final rule.
The compliance date for all applicable emission limitations and operating limitations for the affected units is three years from the effective date of the rule. The compliance date for the sources affected by the current revision to the rule is May 3, 2013. Sources with affected RICE should review the final rule carefully to determine compliance requirements based on the promulgated standard.
