Title: Implementation of Ambient Air Protocol Gas Verification Program.

ICR numbers: EPA ICR No. 2375.01,
OMB Control No. 2060–NEW.

ICR Status: This ICR is for a new information collection activity. An Agency may not conduct or sponsor, and a person is not required to respond to, a collection of information, unless it displays a currently valid OMB control
number. The OMB control numbers for EPA’s regulations in title 40 of the CFR, after appearing in the Federal Register when approved, are listed in 40 CFR part 9 and are displayed either by publication in the Federal Register or by other appropriate means, such as on
the related collection instrument or form, if applicable. The display of OMB
control numbers in certain EPA regulations is consolidated in 40 CFR part 9.

Abstract: This ICR includes ambient air monitoring data reporting and recordkeeping activities associated with the 40 CFR part 58, appendix A, Ambient Air Quality Surveillance Quality Assurance Regulations. These data and information are collected by state, local, and tribal air quality management agencies and reported to
the EPA. The EPA Ambient Air Quality Monitoring Program’s quality assurance requirements in 40 CFR part 58, appendix A, require: ‘‘ 2.6 Gaseous and
Flow Rate Audit Standards. Gaseous pollutant concentration standards (permeation devices or cylinders of compressed gas) used to obtain test concentrations for CO, SO 2 , NO, and

NO 2 must be traceable to either a
National Institute of Standards and Technology (NIST) Traceable Reference Material (NTRM), NIST Standard Reference Materials (SRM), and
Netherlands Measurement Institute (NMI) Primary Reference Materials (valid as covered by Joint Declaration of Equivalence) or a NIST-certified Gas
Manufacturer’s Internal Standard (GMIS), certified in accordance with one of the procedures given in reference 4 of this appendix. Vendors advertising certification with the procedures provided in reference 4 of this appendix and distributing gases as ‘‘EPA Protocol

Gas ’’ must participate in the EPA Protocol Gas Verification Program or not

use ‘‘EPA’’ in any form of advertising. ’’

These requirements give assurance to end users that all specialty gas producers selling EPA Protocol Gases are participants in a program that provides an independent assessment of the accuracy of their gases’ certified concentrations. In 2010, EPA will develop an Ambient Air Protocol Gas Verification Program (AA–PGVP) that will provide end users with information about participating producers and
verification results.

Each year, EPA will attempt to compare gas cylinders from every specialty gas producer being used by ambient air monitoring organizations. EPA Regions 2 and 7 have agreed to provide analytical services for verification of 40 cylinders/lab or 80 cylinders total/year. Cylinders will be verified at a pre-determined time each quarter.

In order to make the appropriate selection, EPA needs to know what specialty gas producers are being used by the monitoring organizations. Therefore, EPA needs information from each primary quality assurance organization every year on specialty gas producers being used and whether the monitoring organization would like to participate in the verification for the upcoming calendar year.

Burden Statement: The annual public reporting and recordkeeping burden for
this collection of information is estimated to average 20 minutes per response. Burden means the total time, effort, or financial resources expended by persons to generate, maintain, retain, or disclose or provide information to or

**SUPPLEMENTARY INFORMATION :** 

I. Background: Several heavy duty diesel engine manufacturers have recently begun utilizing a NO X emission control technology called selective catalyst reduction (SCR) to meet EPA standards and other requirements. SCR is an established technology that has been shown to meet stringent emissions requirements while enabling fuel efficiency benefits.

Currently certified heavy-duty engines utilizing SCR use a nitrogen containing reducing agent (aqueous urea) injected into the exhaust gas upstream of the catalyst. Other types of reducing agents may also be used by SCR technology. The reducing agent needs to be replenished periodically. Without the reducing agent, the efficiency of the SCR catalyst drops to
zero and NO X emissions can potentially increase substantially. The efficiency of the SCR system can also be affected by the use of improper reducing agent or tampering with the SCR system.

The need to replenish the reducing agent (hereafter called diesel exhaust fluid, or DEF, although the reducing agent need not be fluid) and the possibility that SCR technology could be rendered ineffective by operation on an empty DEF tank are addressed by EPA’s existing regulations regarding allowable and necessary maintenance and adjustable parameters. These regulations also apply in the case where inadequate
DEF could be used or where the SCR system may be subject to tampering. Certified engine configurations include provisions and inducements designed to address these regulatory concerns.

EPA has previously provided guidance to heavy-duty diesel engine
manufacturers in March 2007 and
December 2009 to facilitate manufacturer planning in advance of
certification. 1 In addition, in November 2009 EPA published in the Federal Register the approval of specific
maintenance intervals for DEF refills for
certain manufacturers. 2

II. Public Workshop: EPA is commencing a public process designed to provide a thorough review of EPA’spolicies regarding the operation of SCRequipped heavy-duty diesel engines without DEF, with improper DEF, or when tampering (or some other defect in the SCR system) is detected for future 2011 and later model year engines, in order to ensure, among other things, that SCR-equipped engines are designed to properly control emissions as required under applicable law and regulations. Although EPA has previously provided guidance to manufactures regarding the
initial introduction and certification of SCR-equipped heavy-duty diesel engines, consistent with past practice we believe it is appropriate for EPA to review and reexamine its policies as technologies are introduced into the market place. As part of this process, EPA intends to review any information
that has become available to determinewhether its policies regarding SCRequipped engines should be revised. The scope of the review includes review
of the ‘‘Revised Guidance for Certification of Heavy-Duty Diesel Engines Using Selective Catalyst Reduction (SCR) Technologies’’ dated December 30, 2009. As part of EPA’s
