assessment of the secondary NAAQS for 

NOX and SOX. 

As part of the NAAQS reviews, the 

National Center for Environmental 

Assessment (NCEA) within EPA’s Office 

of Research and Development (ORD) 

will assess newly available scientific 

information in Integrated Science 

Assessment (ISA) documents (formerly 

known as Air Quality Criteria 

Documents) that will be supported by 

more detailed and comprehensive 

annexes. The assessments in these 

documents are intended to provide the 

scientific bases for the reviews of the 

NAAQS. EPA’s Office of Air Quality 

Planning and Standards (OAQPS) will 

prepare risk and exposure assessment 

analyses, as appropriate, drawing upon 

the scientific evidence summarized in 

the ISA. Subsequently, the EPA expects 

to prepare a policy assessment, to be 

published as an advance notice of 

proposed rulemaking, that will discuss, 

in part, the findings of the science and 

risk/exposure assessments related to the 

adequacy of the standards and describe 

a range of options for revising or 

retaining the NAAQS. 

EPA is holding this workshop to 

inform the Agency’s assessment of the 

scientific evidence for the review of the 

secondary NAAQS for NOX and SOX. 

The workshop will address various 

issues involved in the preparation of the 

draft material for the ISA and annexes. 

This workshop is planned to help 

ensure that the ISA provides an up-todate, state-of-the-art scientific basis for 

the review of the NAAQS. Workshop 

discussions will be focused on 

identifying and integrating scientific 

evidence that is relevant for future risk 

and exposure analyses to include in the 

ISA. 

This workshop is being held in 

conjunction with a workshop entitled 

‘‘Workshop to Discuss Policy-Relevant 

Science to Inform EPA’s Integrated Plan 

for the Review of the Secondary 

Particulate Matter (PM) National 

Ambient Air Quality Standards 

(NAAQS)’’ (see accompanying Notice of 

Workshop).

Review of the Secondary Particulate 

Matter (PM) National Ambient Air 

Quality Standards (NAAQS)’’ is being

SUPPLEMENTARY INFORMATION: 

I. Summary of Information About the 

Workshops 

The U.S. Clean Air Act requires that 

EPA carry out periodic reviews of the 

national ambient air quality standards 

(NAAQS) for major ‘‘criteria’’ air 

pollutants and to revise the NAAAQS 

for a given pollutant, as appropriate. 

The Agency’s last review of the PM 

NAAQS was completed in September 

2006 with the promulgation of revisions 

to some aspects of the PM standards to 

provide requisite protection of public 

health and welfare (71 FR 61144, 

October 17, 2006). Initiating the next 

review of these standards at this time is 

consistent with the Clean Air Act’s 

requirement that the Agency 

periodically review the latest scientific 

information and the standards. It is also 

consistent with the Agency’s new 

NAAQS review process. For more 

information on the NAAQS review 

process, please see http://www.epa.gov/ 

ttn/naaqs/. 

The workshop will provide an 

opportunity for external experts as well 

as EPA staff to highlight significant new 

and emerging research, and to make 

individual recommendations to the 

Agency regarding the design and scope 

of the review for the secondary (welfarebased) PM standards to ensure it 

addresses key policy-relevant issues and 

considers the new science relevant to 

informing our understanding of these 

issues. A similar workshop to discuss 

planning for the review of the primary 

(health-based) PM NAAQS will be held 

on July 11, 12, and 13, 2007 in Research 

Triangle Park, North Carolina. Please 

see the announcement elsewhere in 

today’s Federal Register. 

Based in large part on the input 

received during the primary and 

secondary PM workshops, EPA intends 

to develop a draft integrated PM 

NAAQS review plan that will outline 

the schedule, process, and approaches 

for evaluating the relevant scientific 

information and addressing the key 

policy-relevant issues to be considered 

in this review. The Clean Air Scientific 

Advisory Committee (CASAC) will be 

asked to conduct a consultation with the 

Agency on the draft integrated plan later 

this year, and the public will have the 

opportunity to comment on the draft 

integrated plan as well. The final 

integrated plan will be used to frame 

each of the major elements of the PM 

review under the new NAAQS process: 

An integrated science assessment 

document, a risk/exposure assessment 

report, and a policy assessment to be 

published as an advance notice of 

proposed rulemaking (ANPR).

Immediately following this workshop, 

EPA is sponsoring a workshop entitled 

‘‘Oxides of Nitrogen and Sulfur (NOX/ 

SOX) Secondary National Ambient Air 

Quality Standards (NAAQS) 

Workshop.’’ These workshops are being 

held in close coordination because EPA 

has recognized that some overlap is 

likely in the issues discussed and areas 

of expertise involved in the review of 

secondary standards for PM, Oxides of 

Nitrogen (NOX), and Sulfur Oxides 

(SOX).

Colorado State Plan for Certification of 

Applicators of Restricted Use 

Pesticides; Notice of Approval 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Notice. 

SUMMARY: In the Federal Register of 

December 22, 2006, EPA issued a notice 

announcing its intent to approve an 

amended Colorado State Plan for the 

certification of applicators of restricted 

use pesticides contingent upon 

Colorado’s promulgation of appropriate 

revised State Rules and Regulations 

pertaining to the Administration and 

Enforcement of the Colorado Pesticide 

Applicators’ Act by January 1, 2007. In 

that notice, EPA solicited comments 

from the public on the proposed action 

to approve the amended Colorado State 

Plan. The amended Certification Plan 

Colorado submitted to EPA contained 

several statutory, regulatory, and 

programmatic changes to its current 

Certification Plan. The proposed 

amendments provide details for the 

certification of both private and 

commercial pesticide applicators and 

subsequent enforcement of pesticide 

laws and regulations pursuant to the 

Colorado Pesticide Applicator’s Act. In 

addition, the amended State Plan adds 

three new commercial pesticide 

applicator subcategories. No comments 

were received in response to that 

Federal Register notice and Colorado 

promulgated the appropriate revised 

State Rules and Regulations pertaining 

to the Administration and Enforcement 

of the Colorado Pesticide Applicators’

Act on January 1, 2007. Therefore, EPA 

hereby approves the amended Colorado 

State Plan.
