Partial Removal of Direct Final Rule 

Revising the California State 

Implementation Plan, Monterey Bay 

Unified Air Pollution Control District 

and San Joaquin Valley Air Pollution 

Control District 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Partial removal of direct final 

rule. 

SUMMARY: On January 2, 2008 (73 FR 

48), EPA published a direct final 

approval of revisions to the California 

State Implementation Plan (SIP). These 

revisions concerned local rules that 

address circumvention, reduction of 

animal matter, and volatile organic 

compound (VOC) emissions from 

gasoline bulk storage tanks, gasoline 

filling stations, petroleum refinery 

equipment, and petroleum solvent dry 

cleaning. The direct final action was 

published without prior proposal 

because EPA anticipated no adverse 

comment. The direct final rule stated 

that if adverse comments were received 

by February 1, 2008, EPA would publish 

a timely removal in the Federal 

Register. EPA received a timely adverse 

comment. Consequently, with this 

revision we are removing the direct final 

approval of SJVAPCD Rules 4104, 4402, 

4404, 4453, 4454, 4625, 4641, and 4672. 

EPA will either address the comments 

in a subsequent final action based on 

the parallel proposal also published on 

January 2, 2008 (73 FR 48) or repropose 

an alternative action. As stated in the 

parallel proposal, EPA will not institute 

a second comment period on a 

subsequent final action. The other rules, 

MBUAPCD Rules 415, 418, and 1002, 

approved in the January 2, 2008 direct 

final action, are not affected by this 

removal and are incorporated into the 

SIP as of the original effective date of 

March 3, 2008. 

DATES: The addition of 40 CFR 

52.220(c)(351)(i)(C) published at 73 FR 

48 on (January 2, 2008) is removed 

effective March 13, 2008.

In-Use Testing for Heavy-Duty Diesel 

Engines and Vehicles; Emission 

Measurement Accuracy Margins for 

Portable Emission Measurement 

Systems and Program Revisions 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Direct final rule. 

SUMMARY: In a rule published on June 

14, 2005, EPA established a 

manufacturer-run, in-use testing 

program for heavy-duty diesel vehicles. 

The program requires engine 

manufacturers to measure exhaust 

emissions from their diesel engines 

using portable emissions measurement 

systems during real-world operation. At 

the time the rule was promulgated, EPA 

established interim emission 

measurement ‘‘accuracy’’ margins for 

the requisite portable emission 

measurement devices pending the 

development of final accuracy margins 

through a comprehensive research 

program. This Direct Final Rule adopts 

the resulting final accuracy margins for 

gaseous pollutants. Also, this rule 

makes several changes to the program in 

the early years of in-use testing. First, 

we are eliminating the first calendar 

year, i.e., 2006, of the two-year pilot 

program for particulate emissions (PM) 

in response to engine manufacturers’

concerns, which primarily relate to the 

availability and efficacy of the requisite 

portable measurement systems (PEMS) 

for that pollutant. Second, due to a 

delay in developing the final accuracy 

margin for PM under the 

aforementioned comprehensive research 

program, we are delaying the first year 

of the fully enforceable PM test program 

from the 2008 calendar year to the 2009 

calendar year. During the 2008 calendar 

year, there will be another year of pilot 

program testing for that pollutant. 

Third, and finally, we are extending the 

normal period for reporting in-use test 

results during the initial years of the 

program and allowing certain short-term 

changes in how vehicles are recruited 

and tested. These revisions are 

primarily intended to address delays in 

initiating the gaseous emission and PM 

pilot programs, manufacuturers’

concerns regarding the schedule for 

initial purchases of PM measurement 

systems, and manufacturers’ concerns 

regarding potential difficulties of 

initially instrumenting vehicles with 

these units. 

DATES: This is effective on May 12, 2008 

without further notice, unless EPA 

receives adverse comment by April 14, 

2008. If EPA receives adverse comment, 

we will publish a timely withdrawal of 

the Direct Final Rule in the Federal 

Register informing the public that the 

rule will not take effect.
