New Source Review Reform Rulemaking Meeting 

See Attachment 1 

INTRODUCTION 

A New Source Review (NSR) meeting was held on January 30, 1998 between the 

U.S. Environmental Protection Agency (EPA) and stakeholders participating in the rulemakings. 

The purpose of the meeting was to continue discussing the issues surrounding Class I provisions 

of the NSR Reform rulemaking effort. Particular issues discussed included: 

• Federal Land Manager's (FLM's) hierarchial view of Air Quality Related Value 

(AQRV) issues; 

• AQRV monitoring; and 

• Stakeholder viewpoints on NSR reform elements. 

A brief summary of the issues discussed is presented below. 

HIERARCHY OF AQRV ISSUES 

The FLMs are preparing a memorandum describing their perspective on Class I issues, 

including their hierarchy of AQRV informational issues. FLMs provided a brief summary of their 

hierarchy of AQRV informational issues, which included: 
J 

P.4 

AQRVs; 

• AQRVs of concern; 

• Level of adverse impact; and 

• Screening level values. 

The first level in the hierarchy is identifying AQRVs. For most parks, AQRVs have 

already been identified and are consistent with the definition in the proposed rule. The proposed 

AQRV definition is the same definition FLMs have used previously for Class I analyses. The list 

of AQRVs, however, is not the FLM's focus in a Class I analysis. 

The second level in the hierarchy is where the FLM's Class I analysis is focused. The 

second level is identifying AQRVs of concern. AQRVs of concern are those AQRVs most 

sensitive to air pollution and the indicators of the potential for an adverse impact. AQRVs of 

concern are available and can be provided by the FLMs. 

Identifying the level of adverse impact on an AQRV of concern is the third level in the 

FLM hierarchy. The level of adverse impact is the deleterious or unacceptable level of change to 

an AQRV. In some parks, site-specific information is available and the level of adverse impact 

can be clearly identified. In other parks, site-specific research is not available, therefore, it is more 

difficult to identify the level of adverse impact. The FLM goal is to provide either site-specific 

information or to rely on a regional default. 

The final and most difficult level in the FLM hierarchy is identifying screening level values. 

This is the level where responsibility for an impact on a park is assigned to a permit applicant. 

Several models exist which may be used in making such a determination, however, this hierarchial 

level is still being evaluated.

P.5 

AQRV MONITORING 

In addition, the FLMs believe that a means to monitor the impacts on AQRVs to 

determine when a critical load has been reached is needed, as well as a means to monitor progress 

when a critical load has been reached. FLMs feel that EPA and stakeholders need to devise and 

support a plan to obtain the necessary monitoring in all Class I areas. 

STAKEHOLDER VIEWPOINTS ON NSR REFORM ELEMENTS 

EPA provided a written summary of stakeholder viewpoints on the significance of NSR 

reform elements discussed at the January 13, 1998 meeting between EPA and stakeholders and 

requested confirmation of the accuracy of the summary. Stakeholders identified any necessary 

changes to the summary. 

CONCLUSIONS AND NEXT STEPS 

The Agency meets with a subcommittee of the Clean Air Act Advisory Committee 

(CAAAC) on Tuesday, February 17, 1998, and would like to discuss the Class I issues as well as 

other NSR Reform issues. The FLMs agreed to complete their Class I issues memorandum for 

discussion with EPA and stakeholders at the next meeting of this stakeholder group prior to the 

CAAAC subcommittee meeting. The next stakeholder meeting was scheduled for Thursday, 

February 12, 1998 at 4:00 p.m. eastern standard time. The telephone call-in number is (919) 541-

4345. The participants also agreed that further discussion of plant wide applicability limits 

(PALs) and pollution control project exclusions (PCPEs) would benefit EPA as well as 

stakeholders. The Agency agreed to schedule a meeting to discuss these issues.
