SUBJECT:	Summary of the December 15, 2010 Meeting with API Regarding CPMS Issues in Petition to Reconsider on RICE NESHAP

--------------------------------------------------------------------------------

INTRODUCTION

      The American Petroleum Institute (API) requested this meeting with EPA to discuss the petition for reconsideration submitted by API on the National Emission Standards for Hazardous Air Pollutants (NESHAP) for stationary reciprocating internal combustion engines (RICE).  The most recent amendments to the NESHAP for stationary RICE were published in the Federal Register on August 20, 2010 (75 FR 51570).

SUMMARY OF MEETING 

	API submitted a petition for reconsideration on October 19, 2010 on the stationary RICE NESHAP (EPA-HQ-OAR-2008-0708-0582).  The petition included a request for reconsideration on the monitoring requirements that were included in the August 20, 2010 final rule.  Specifically, API requested this meeting with EPA to discuss the continuous parametric monitoring system (CPMS) requirements that apply to existing stationary engines.  API provided an agenda for the meeting of CPMS issues it wanted to discuss, which follows this meeting summary.

	API indicated that it has concerns with the short and long-term impacts of the CPMS requirements for stationary engines, particularly with the short-term impacts because stationary engines at major sources that were originally covered under the 2004 rule will have to comply with these requirements in the near future.  According to API, there is inadequate time to implement the CPMS requirements for major sources.  API indicated that its long-term concerns are more related to existing stationary engines at area sources.  API was eager to assess how to reach productive next steps to resolve the issues associated with the CPMS requirements.

	According to API, 100 percent data capture is virtually impossible.  API indicated that it is not aware of any other EPA regulation that requires total data capture.  For instance, power failures and system reboots alone will make total capture of monitoring data impossible.  According to API, the 100 percent data capture requirement is impractical and the organization disagrees with this requirement.  Many EPA rules require 90 to 95 percent data capture and some require 70 percent data capture, according to API.  Further, API asked if every 15-minute increment would be a deviation and if the engine would be out of compliance if the data was not available.  In API's opinion, the lack of data does not necessarily mean that the engine was actually out of compliance.  API also indicated that the initial calibration of thermocouples would be problematic to complete within 90 days.  (This requirement relates to obtaining inlet catalyst temperature readings.)

	In terms of issues related to CPMS requirements for engines at area sources, API argued that there are a number of parameters at particularly rural area sources that are compelling reasons for not requiring CPMS at these locations.  Rural sites are often not manned, they may lack electricity, and it may be difficult to install and maintain controls at these remote sites, according to API.  Sites would necessitate reliable power sources in order to properly fulfill CPMS requirements and some rural sites do not have power at all.  In addition, many rural sites do not have communication access, which is another limiting factor.  Also, determining accurate load is not possible at many sites, e.g., in some cases an operator would be unable to measure the flow per engine because the engine is grouped with other engines.  Good infrastructure is needed and API indicated that it believes it is more of an issue with rural sources.  API indicated that it is technically feasible, but that it is not economically feasible and argued that EPA needs regulatory and economic justification for the CPMS requirements.

	API noted that it had provided comments on the original CPMS rule that have not been addressed.  In addition, there was no opportunity for comment on the engine CPMS requirements since it was just added to the final rule.  API recommended that EPA issue an administrative stay for the CPMS requirements specifically and asked what it could provide to assist EPA delaying the requirements for major sources.  

      EPA noted that it is open to continued discussion and asked how the CPMS requirements in the final rule are different from how owners and operators of stationary engines are currently capturing monitoring data.  API could not provide a specific answer, but indicated that based on OECA's 2005 Questions and Answers document, there are companies that are not monitoring catalyst inlet temperature at all or if they are capturing data, companies are capturing 95 percent of the data at most.  API indicated that it would send a formal letter to EPA describing the specific issues it is requesting an administrative stay.  A follow-up meeting with API is scheduled for January 6, 2011 to further discuss these issues.

Discussion of CPMS Issues in Petition to Reconsider Reciprocating Internal Combustion Engine NESHAP, Final Rule, 75 Fed. Reg. 51,570 
                                       
1:00	Introductions & Meeting Objectives  -  Eliminate CPMS Requirements for Area Sources
         Technical Concerns/Deficiencies
                    *             Data availability requirements (100% data capture)
                    *             "Deviation" implications 
                    *             Thermocouple calibration requirements 
         Area Source Monitoring Compliance Implementation Issues 
         
                    *             Area sources urban vs rural 
                    *             Lack of site power
                    *             Site communication access is limited at area sources
                    *             Must be able to integrate with other monitoring equipment within a field.
                    *             Must be integrated with other field monitoring equipment and meet industry and company standards
                    *             Installation in weatherproof containers
                    *             Determining load during monthly differential pressure monitoring is impractical at area sources 
         Need / Justification for Inclusion of CPMS and monitoring in August 2010 Area Source Rule
                    *             Addition of CPMS specifications without opportunity for public comment
                    *             CPMS specifications did not respond to ACC/API comments on CPMS of February 5, 2009 where applicable.
                    *             Maintenance and calibration of new data and monitoring equipment at remote area sources is difficult and costly. 
                    *             Area source cost/benefit comment does not match actual O&G site limitations and CPMS specification.
            
         Inadequate Implementation Time for 2004 RICE MACT Systems at Major Sources and Need for Administrative Stay of Performance Specifications and Calibration Standard 
         Schedule Next Meeting to Discuss Other Issues Outlined in the Petition for Reconsideration
