RE: Revision to the Oregon State Implementation Plan: Infrastructure Rule Changes 

Dear Mr. McLerran: 

The Oregon Department of Environmental Quality requests approval of revisions to, the Oregon 

State Implementation Plan (SIP) from the Office of Air, Waste, and Toxics, State arid Tribal Air' 

Programs Unit of the U.S. EPA, Region 10. Copies of the amendments are submitted for your 

reVIew. 

The Environmental Quality Commission adopted the revisions to the SIP under OAR 340-200-

0040 on April 30, 2010. DEQ submits these revisions to EPA as part of the SIP and pursuant to 

40 CFR 51.104. 

I certify that public notices were published in newspapers of general circulation on November 

17,2009, and in the Secretary of State's Oregon Bulletin on December 1,2009. The notices 

included a statement that adoption of the rules would revise the SIP. I further certify that a 

public hearing was held on December 18, 2009 in Oregon. 

Thank you for your assistance with these revisions to Oregon's SIP. The staff contact for this 

submittal is Carrie Capp, Air Quality Planning, at 503-229-5035, and Margaret Oliphant, SIP 

Coordinator, at (503) 229-5687.

OAR Chapter 340, Divisions 200,202,204, and 206 

April 29-30, 2010 EQC meeting 

Updates to the Oregon State Implementation Plan are needed to ensure that Oregon 

has the appropriate rules, tec~cal documentation and agreements in place to 

implement the federal Clean AJr Act The proposed rule revisions update Oregon's 

infrastructure State Implementation Plan allowing f9r EPA approval. The rule 

packag~ also contains other ·changes to align DEQ and EP A rules. . 

DEQ 

recommendation 

andEQC 

The Department of Environmental Quality recommends that the Oregon 

Environmental Quality Commission adopt proposed rule revisions and report on 

interstate transport as presented in attachments A and B and authorize DEQ to 

submit them to the U. S. Environmental Protection Agency as revisions to the 

Oregon State Implementation Plan. 

motion 

Background and 

need for ' 

ruIemaking 

Effect of rule 

Sections 11 O( a)( 1) and (2) of the federal Clean Air Act requires states to submit 

changes to state implementation plan infrastructure elements to EPA for approval. 

A state implementation plan is a state plan for implementing portions of the Clean 

Air Act, and consists of narrative, rules, technical documentation and agreements. 

States maintain, and periodically update their plans to incorporate new 

req~~~~ep:~s-;:-and-t:f>~-must-=-app!oye-eac!1-r~!ts!(m. 

. Between 2005 and 2008, EPA issued findings that states had not fully brought ' 

their state implementation plans up to date to address interstate transport of ozone 

and fine particulate, PM2.5, EPA's promulgation of the 1997 ozone health . 

standards and EP A.' s promulgation of the 1997 PM2.5 health standards. In 2008, A; 

DEQ and EPA reviewed Oregon's pla~ for ozone and PM2.5• DEQ and EPA have 

identified the rulemaking actions described below as needed updates to help 

ensure EPA's approval of the Oregon State Implementation Plan. 

This proposed rulemaking would update several rules as necessary to meet 

requirements of the federal Clean Air Act for Oregon's state implementation plan 

infrastructure. These revisions include: 

• Recently adopted.federal changes to National Ambient Air Quality 

Standards for PM2.5, ozone and lead;

Stakeholder 

involvement 

Public comment 

Key issues 

• Oregon's evaluation of interstate transport ofPM2.5 and ozone; 

• Incorporating into the plan the definition of PM2.5, currently in Oregon 

rule; . 

• PM2.5 non-attainment area boundary descriptions for the cities of Klamath 

Falls and Oakridge; 

• . Revised PM2.5 thresholds for significant harm, for triggering air quality 

warnings, alerts and emergencies; and 

• Revision to the definition of volatile organic compound to exenipt 

dimethyl carbonate and propylene carbonate, consistent with recent federal 

actions. 

The commission has authority to take this action under DRS 468.020, ORS 

468A.025 and ORS 468A.035. 

Stakeholders were given the opportunity to provide input during the public hearing 

and comment period. Their comments are attached. 

DEQ held a public comment period Nov. 17, 2009 to Dec. 22, 2009 and included 

a public hearing in Portland. No one attended the hearing and DEQ received one 

conunent on the proposed rule. A summary of public comment received and 

DEQ's response is provided in attachment C. 

Volatile organic compounds 

EPA has found that the volatile organic compounds dimethyl carbonate and 

propylene carbonate have low photochemical reactivity and are, therefore, not 

significant contributors to ozone formation. EPA has exempted both compounds 

from the definition of volatile organic compound for pui:poses of ozone, and DEQ 

proposes to also exempt ·these compounds. This exemptio1;l. could lead to increased 

use of these compounds as solvents in paints or other products. Currently, these 

two compounds are not listed hazardous air pollutants, nor are they potent 

greenhouse gases relative to other alternatives currently in use. If concerns arise 

about these compounds in the futUre," DEQ can regulate them as needed throug~ 

the air toxics or greenhouse gas programs. 

Significant harm levels 

Significant harm levels are set at a level of air pollution that represents imminent 

and substantial endangerment to public health. These levels are far above National 

Ambient Air Quality Standards, which are the general safeguard for public health. 

Significant harm levels can be used to respond to o-ccasional extreme pollution 

events, such as forest fire smoke. Approaching or exceeding a significant harm 

level would trigger communication with local governments and the public about 

health concerns and actions to be taken. DEQ must add significant hann levels for 

PM2.5 to its rules, and -yvill use the PM2.5 significant harm levels proposed by EPA.

Interstate transport 

The Oregon State Implementation Plan must include an assessment of the extent 

to which Oregon emissions cause or contribute to violations of ozone' and PM2.

5 

health standards in neighboring states. DEQ's report, seen in attachment B, 

provides DEQ's assessment ,and conclusion, based on existing information that air 

emissions from Oregon do not cause or contribute to violations of ozone or PM2.5 

standards in neighboring states. EPA has reviewed and commented on DEQ~ s 

proposed document. DEQ's assessment is based on the current ozone and PM2.5 

standards. It is likely that EPA will tighten both of these standards in the future. At 

that time, states will reassess interstate transport as part of the necessary state 

implementation plan update. 

If adopted, these proposed rules will be filed with the Secretary of State and 

submitted to the EPA for review and approval. The proposed rule changes will 

become effective in Oregon upon EQC approval. The state implementation plan 

will be officially revised when EPA publishes its approval in the Federal Register.

that the DEQ has the ability to implement requirements of the Clean Air Act. EPA has requested that the DEQ make the 

proposed rules updates as a revisions to the infrastructure SIP in relation to the new PM2.5 and ozone standards. 

Revisions to the SIP include: 

• Updated state standards for particulate matter, lead and ozone, to reflect recent changes to national ambient air quality

• Proposed new Significant Harm Levels for PM2.5. 

• Proposed exemption from the definition of Volatile Organic Compounds (VOC) for Di!llethyl Carbonate, consistent

Petition to Oregon DEQ to exempt Propylene Carbonate (CAS# 108-32-7) from the 

definition of Volatile Organic Compound (VOe} in OA~ 340, Division 200. U.S. EPA 

exempted Propylene Carbonate from their definition of a VOC on January 21, 2009 

(Docket 10 No. EPA~HQ-OAR-2006-0948) on the basis that the compound makes a 

negligible contribution to tropospheric ozone formation.
