In November 1999, the U. S. Environmental Protection Agency ( EPA) is proposing to approve attainment demonstrations for the following ten serious and severe ozone nonattainment areas:

Serious Areas ! Atlanta, GA ! Greater CT ! Springfield, MA ! Washington, DC Severe Areas ! Baltimore, MD ! Chicago, IL ! Houston, TX ! Milwaukee, WI ! New York City Metro ! Philadelphia, PA Many of these areas are located in States which will need to adopt additional control measures to support EPA's approval of their attainment demonstrations for these areas. The EPA is providing the information in this report specifically to help these States in the task of identifying and adopting the additional control measures. This document is not intended to recommend any particular control measure or emission reduction strategy.

The information is provided in four areas. First, the report contains detailed information on emissions for ozone precursor emissions of nitrogen oxides ( NOx) and volatile organic compounds ( VOCs). Second, the report contains information on available control measures for emission sources of NOx and VOCs. Third, the report includes information on Clean Air Act standards or guidance that EPA has issued in three areas: alternative control technology ( ACT) documents, New Source Performance Standards ( NSPS), and Maximum Achievable Control Technology ( MACT) standards. These standards and guidance will help reduce VOCs and NOx, which contributes to the ability of these areas to attain. Finally, the report includes information on the control measures these areas have adopted, or are planning to adopt, into their SIPs.

3.0 Available Control Measures The attached Table 11 includes control measures which States may want to consider for adoption to help the ten serious and severe 1 hour areas demonstrate attainment. The list consists of: 6 1) VOC and NOx emission sources with control measures for which EPA has not issued Clean Air Act standards or guidance. 2) VOC and NOx emission sources with control measures which States already control at a reasonably available control technology ( RACT) level. 3) Clean Air Act standards or guidance that EPA has issued in three areas: ACT documents, NSPS, and MACT standards.

In addition to Table 11, States can consult information on best available control technology ( BACT) and lowest achievable emission rate ( LAER) determinations that States have made for individual new sources. Information on BACT/ LAER determinations is available through EPA's RACT/ BACT/ LAER Clearinghouse ( RBLC) which may be accessed on EPA's web site on the internet at the following web address: http:// www. epa. gov/ ttn/ catc/.

3.1 VOC and NOx Emission Sources with Control Measures ( a) for Which EPA Has Not Issued Clean Air Act Standards or Guidance or ( b) Which States Already Control at a RACT Level The EPA is providing this list because it contains measures which States may want to consider for adoption to help the serious and severe 1 hour areas demonstrate attainment. This list should be considered a starting point for finding additional control measures and not a comprehensive list of all possible measures which may be available. For purposes of the 1 hour attainment demonstrations, EPA is not suggesting that States evaluate each and every one of these measures. States are also not limited to this list of measures when evaluating or adopting additional control measures for the 1 hour attainment demonstrations. In addition, some of the measures identified are listed as voluntary. For these measures, areas may want to encourage citizen participation without necessarily making the measures mandatory.

In some cases, the measures appear to control an industry which is already well controlled. However, in these cases, the measure may recommend a tighter limit or a lower capacity cutoff that is common in current regulations. Such tighter limits may be feasible with modern technology and could provide an opportunity for increased pollution control compared to current practice. It is advised that readers check the source listed in the bibliography for a more in depth description of the type of control technology which is being discussed.

The EPA has not investigated all of these measures to determine their cost effectiveness or technical feasibility. However, the fact that some type of governmental group has listed the measure shows that it has received some prior scrutiny. In some instances, States may have adopted these measures. In other cases, States may not have adopted these measures or some States may have adopted these measures at a different level of emission reduction than indicated in the table.

The list in Table 11 includes measures taken from twelve sources of measures compiled by governmental entities or governmental body associations. Details on these sources are provided 7 with Table 11. The descriptions given of each measure in the table are brief. Briefly, the sources of the measures are:

1) Arizona Department of Environmental Quality. 2) California's Air Resources Board. 3) California Federal Implementation Plan. 4) Illinois Environmental Protection Agency. 5) Office of Mobile Sources, EPA. 6) Office of Air Quality Planning and Standards, EPA. 7) Smart Growth Network. 8) South Coast Air Quality Management District. 9) STAPPA/ ALAPCO. 10) Texas Natural Resources Conservation Commission. 11) EPA, TTN Website, Unified Air Toxics Website. 12) EPA, TTN Website, States' NOx RACT Rules 3.2 Clean Air Act Standards or Guidance Part of Table 11 consists of ACTs, NSPSs and MACT standards issued by EPA.

3.2.1 Alternative Control Technology Documents Table 11 includes a list of ACT documents for VOC control which EPA has issued. The documents do not formally define RACT, but describe available measures that are technologically feasible along with the costs of control which States can adopt to satisfy RACT. ( Unlike ACTs, control technique guidelines ( CTGs) do define RACT, which the Clean Air Act requires ozone nonattainment areas to adopt.) Many States have adopted rules for these sources for which the ACT documents may identify an additional level of control. In other cases, States may not have adopted rules. Therefore, new State rules for these sources may provide an opportunity for additional VOC control for the 10 areas. Finally, the ACTs may provide control options for nonmajor sources not covered by RACT within these source categories.

Table 11 also provides a list of EPA's NOx ACTs. A number of cost effective techniques is described which give NOx controls at more strict levels of controls than have been adopted by most States. Only some States have adopted rules for these sources. Therefore, new or more stringent State rules for these sources may provide an opportunity for additional NOx control for the 10 areas. In addition to ACTs, some other relevant NOx control reports are also listed.

3.2.2 New Source Performance Standards Table 11 provides a list of EPA's NSPSs, which address the control of VOCs. In many cases, the NSPSs cover industries which were previously covered by CTGs, but the NSPS specifies a more stringent level of control. The more stringent level of control has been justified 8 by the fact that the NSPSs apply to new sources or significantly modified existing sources. The more stringent level was also justified because the more stringent control technology could be designed into the new installations at lower cost than the cost of applying the same level of control to existing sources. As control technology techniques have improved, some of the NSPS control levels may be applicable to existing sources at reasonable cost levels.

Generally, in many of the CTGs EPA recommends a control level that is about an 81 percent reduction in emissions from the uncontrolled emission levels. Often the NSPS level of control is 90 to 95 percent. Thus, the NSPS level would provide about an additional 10 percent control. This additional reduction is an area States may wish to investigate in deciding how to find additional emissions reductions for the 10 areas. However, the opportunity for additional control is not always available. For example, the automobile coating NSPS does not appear to be more stringent than the CTG due to transfer efficiencies that were specified in the NSPS. Finally, additional control may be obtained from existing sources by specifying a lower cutoff value for exemption from NSPS control.

3.2.3 Maximum Achievable Control Technology Standards Table 11 also provides information on EPA's MACT standards. Many of these standards have been issued or are scheduled to be issued by November 2000. The MACT standards are designed to control hazardous air pollutants ( HAPs). They are developed by examining the average of the best 12 percent of existing sources. In some cases, MACT levels of control have been set at the same level as CTGs. This is especially true for industries such as aerospace and shipbuilding surface coating for which the CTG and MACT standards were developed concurrently.

We are providing the MACT information because there may be some opportunities in three areas for additional VOC control for source categories subject to a MACT standard. First, since many HAPs are VOCs, a MACT standard may control all VOCs, including the VOCs which are also HAPs. This would usually be the case when an add on control device such as an incinerator is used. In this case the MACT level of control, which would often be more stringent than the CTG level, would apply to the total VOC emissions. However, in some situations, such as coatings reformulation, the HAPs can be removed without affecting the other VOCs. For example, a source might choose to use a non HAP solvent as a substitute for a previously used solvent that is classified as hazardous. The result of this substitution would be that the source would eliminate the HAPs without having to control the VOCs. To achieve greater VOC control, a State could write a rule that would control all VOCs to the same extent that the current MACT rule limits HAPs. Reducing the other VOCs may be an option States wants to consider in evaluating where to find additional emissions reductions for the 10 areas.

Second, MACT standards may control to a more stringent level than RACT, as prescribed in a CTG. These higher levels of control could be applied to existing sources. Third, additional control may be obtained from existing sources by specifying a lower cutoff value for exemption 9 from MACT control.
