Date: May 5, 2003 Subject: Revised MACT Floor, Regulatory Alternatives, and Nationwide Impacts for Equipment Leaks at Chemical Manufacturing Facilities Miscellaneous Organic NESHAP EPA Project No. 95/ 08; RTI International Project No. 08550.001.011 From: Brenda Shine, North State Engineering, Inc. Melissa Icenhour, RTI International David Randall, RTI International To: MON Project Files I. Introduction This memorandum describes existing and new source MACT floors for equipment leaks, regulatory alternatives above the floor and resulting incremental cost effectiveness of going beyond the floor. This analysis was conducted in response to comments received on the April 4, 2002 proposal.

II. Discussion A. Summary of Comments 1. Process Based Approach. The commenters argued that the approach for setting the floor on a facility wide basis, as documented in the MACT floor memorandum may not have adequately addressed variations in level of control of LDAR programs within facilities. 1 The Section 114 information survey requested some specific information about LDAR programs, but did not prompt respondents to specifically identify each LDAR program corresponding to each MON process, if different programs were in use for separate MON processes at the facility. Upon review of our data, we noted that there are circumstances where different processes are controlled by different LDAR programs. Therefore, we reviewed our database and reanalyzed our data on a process basis.

2. Corrections to the Database. Commenters recommended numerous changes to the database. We reviewed suggested changes and revised database entries under the following two circumstances: ( 1) when the process is subject to the HON so that only the batch process vent emissions are subject to the MON and ( 2) when the facility contact indicated to the commenter 2 that a non HON LDAR program or no program is implemented for a MON process. The following specific changes were made to the database:

# Six processes at the Dixie Chemical Company plant were assigned the HON LDAR program in our original database; these have been changed to TX 28MID.

# Three processes at the Exxon Chemical Americas, Bayway Chemical Plant were assigned the HON LDAR program in our original database; these have been changed to NSPS VV.

# Five processes at the Lubrizol, Deer Park Plant were assigned the HON LDAR program in our original database; these have been changed to TX 28 MID.

# Six processes at the Lubrizol, Bayport Plant were assigned the HON LDAR program in our original database; these have been changed to TX 28 MID.

# We deleted entries for two processes at the Velsicol Chemical Corporation Plant that are subject to the HON.

# We deleted entries for three processes at the Kalama Chemical, Inc. plant that are subject to the HON.

# Of 11 processes at the Witco Corp., Sistersville Plant that were assigned the HON LDAR program in our original database, we revised 9 to no LDAR program and assigned the HON LDAR program to 2 processes. We also added two additional processes and assigned no LDAR program.

3. Costs. Commenters argued that the proposed LDAR requirements are not costeffective because the potential environmental benefits are much lower than EPA assumed based on its SOCMI factors. Commenters submitted leak data from their industry to support their arguments. They also listed several basic, and expensive, requirements that would have to be implemented to make an LDAR program effective, such as identifying subject equipment, creating facility drawings, developing and populating a data management system, conducting physical tagging of components, developing a system to coordinate with O& M personnel, assigning personnel to coordinate the program, and training personnel. In arguing cost effectiveness of Method 21 based monitoring, commenters also suggested that our cost analysis was obscured by the inclusions of cost effective elements( design standards and audible/ visual/ olfactory based program) with the Method 21 portion.

B. Revisions 1. Revised MACT Floor. Prior to making the revisions noted above, we analyzed our database on a process basis and found that 85 of the 1,142 processes ( 7.4 percent) in our database were reported to be controlled by HON equivalent LDAR programs. This analysis includes all processes in the database; we did not attempt to identify continuous processes versus batch processes because many processes include both continuous and batch operations. After making 3 the revisions, 51 of 1,139 processes are controlled to the HON LDAR, or 4.5 percent controlled. Based on this result, we could not justify a MACT floor at the HON level of control.

The NSPS subpart VV LDAR was written into 40 CFR Part 63 as subpart TT ( Control Level 1), and the CAR LDAR program was written into Part 63 as subpart UU ( Control Level 2). Therefore, all Part 63 standards can cross reference either subpart TT or subpart UU, depending on the program desired. For MACT standards promulgated after the promulgation dates of subparts TT and UU, options are the adoption of either subpart TT or subpart UU, and not subpart H. The HON subpart H program is an older LDAR program that has been improved on in subpart UU by providing more flexibility and less burden while achieving similar reductions. The differences in moving from subpart H to subpart TT are a change in leak definition from 500 ppmv to 10,000 ppmv for most components, and no Method 21 monitoring for connectors. In moving from subpart H to subpart UU, an allowance is provided for less frequent monitoring based on leak rates.

Therefore, we reviewed the data to determine how many processes were controlled to a level equivalent to Subpart TT. For this analysis, we considered LDAR programs such as TX28MID, 28M, TX28RCT, TX28VHP, TX Reg 5, and LA non HON, as well as processes implementing 40 CFR 60 Subpart VV. Only LDAR programs designated as audible/ visual/ olfactory ( e. g., not Method 21 monitoring) were not considered at least equivalent to subpart TT. We found that 236 of the 1,139 processes, or 21 percent were controlled at least to that level. Therefore, we set the floor for existing sources on the requirements of subpart TT. The floor for new sources is still the requirements of subpart UU.

2. Regulatory Alternative Above the Floor. We conducted an analysis of the cost effectiveness of two regulatory alternatives that are more stringent than the MACT floor. The first regulatory alternative would require subpart UU LDAR for all processes with at least one continuous operation ( i. e., those processes represented by the continuous model process in the previous analysis). The second regulatory alternative would require the subpart UU LDAR program for all processes. In conducting this analysis, we revised our estimated uncontrolled emissions for our model processes by using the initial leak rates submitted by the industry in their comments. 2 At the leak definitions of 500 ppmv for connectors and valves and 1,000 ppmv for pumps, we calculated leak rates of 0.35 percent for connectors, 6.47 percent for pumps, and 1.66 percent for valves from the data submitted by the industry. We also compared these leak rates and their resulting emission rates to data collected in the development of the Polymers and Resins IV standard and found good agreement. The Polymers and Resins industry leak rates were 0.61 percent for connectors, 8.71 percent for pumps, and 1.4 to 1.8 percent for valves. 3 For reductions achieved by the programs, we assumed that the reduction achieved by the subpart UU program would be equal to the emission estimated at the performance level of the program. We assumed that the subpart TT program would be half as effective as subpart UU for pumps, valves, and connectors, and that the reductions for pressure relief valves, open ended lines, and sampling connections would be the same under both programs. A tabular summary of our emission estimates is provided in Table 1. The resulting model plant emission estimates are provided in Table 2. 4 Table 1.

Table 3 presents a summary of changes to the cost elements. The revised analysis assumes that a facility required to implement an LDAR program will hire a subcontractor, based on our understanding that this is the preferred and common alternative over the implementation of an in house program. The analysis makes use of revised data from the project files of the Polymers and Resins IV standard, including specific petitioner comments. Detailed costs for batch and continuous model processes under subparts TT and UU are included in Attachment 1. Attachments 2 through 4 present the Microsoft Access modules that were used to estimate the impacts under the MACT floor and the regulatory alternatives. Note that references to " HON" and " subpart VV" in the attachments mean subparts UU and TT, respectively, for the purposes of this analysis.

Table 3. Revised Cost Elements Cost element Previous analysis UU TT Comments Initial monitoring $/ Comp Pumps $ 4.65 $ 17.70 $ 17.70 The $ 17.70 is based on comments from PET producer Eastman's experiences, which indicated significantly greater initial costs than had been previously assumed; items included in the $ 17.70 are walkdown and field verification, creation and issuance of drawings, creation of data forms and tags, hanging of tags, population of software, cost of tags, and the initial monitoring costs. The original the $ 4.65 was based on $ 2.15/ component for identification and documentation of components and $ 2.50 for initial monitoring. The $ 17.70 cost was assumed to apply to the UU and TT programs for all components requiring M21 periodic monitoring. For connectors subject to TT, and initial cost of $ 1.13 was assumed, the same cost as applied to heavy liquid components in all of the four programs.

Conclusions The changes have reduced the anticipated emission reductions at the MACT floor by almost an order of magnitude while more than doubling the annual costs. The revised cost of the MACT floor for processes represented by the continuous model process is $ 3,180/ Mg, and the incremental cost of the first regulatory alternative ( subpart UU for processes that contain continuous processes) is $ 470/ Mg, both of which are reasonable. The MACT floor cost and incremental cost effectiveness of regulatory alternative 2 ( subpart UU for batch processes), however, are unreasonable. Therefore, we recommend using regulatory alternative 1 as the standard for equipment leaks at existing sources.
