Approval and Promulgation of 
Implementation Plans; Texas; El Paso Carbon Monoxide Limited Maintenance Plan 
AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : Pursuant to the Federal Clean 
Air Act (CAA or the Act), the Environmental Protection Agency (EPA) is proposing to approve the required second carbon monoxide (CO) maintenance plan as a revision to the Texas State Implementation Plan (SIP). The El Paso, Texas CO maintenance area (El Paso Area) has been demonstrating consistent air quality monitoring at or below 85% of the CO National Ambient Air Quality Standard (NAAQS or standard). Because of this, the State of Texas, through its designee, submitted the required second maintenance plan for the El Paso Area as a Limited Maintenance Plan (LMP). 
DATES : Written comments should be 
received on or before April 20, 2017.

Jeffrey Riley, 214–665–8542, riley.jeffrey@epa.gov. SUPPLEMENTARY INFORMATION : In the 
final rules section of this Federal Register, the EPA is approving the State’s SIP submittal as a direct rule without prior proposal because the Agency views this as noncontroversial submittal and anticipates no adverse comments. A detailed rationale for the approval is set forth in the direct final rule. If no relevant adverse comments are received in response to this action no further activity is contemplated. If the EPA receives relevant adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule. The EPA will not institute a second comment period. Any parties interested in commenting on this action should do so at this time.

AGENCY : Environmental Protection 
Agency (EPA). 
ACTION : Proposed rule. 
SUMMARY : Pursuant to the Federal Clean 
Air Act (CAA or Act), the Environmental Protection Agency (EPA) is proposing to approve an error correction to a previously approved diesel inspection and maintenance (I/M) program provision in Albuquerque/ Bernalillo County’s State Implementation Plan (SIP). This action is based on our determination that at the time EPA approved the diesel I/M Program the State did not have the legal authority to expand its program to require the testing of 1998 and newer diesel motor vehicles greater than 1,000 and less than 10,001 pounds.

SUPPLEMENTARY INFORMATION : 
I. Background 
On January 18, 2017, PHMSA 
published an advance notice of proposed rulemaking (ANPRM) titled, ‘‘Hazardous Materials: Volatility of Unrefined Petroleum Products and Class 3 Materials,’’ addressing the volatility of unrefined petroleum products and potentially all Class 3 flammable liquids transported by means other than pipeline. See (82 FR 5499). The ANPRM 
informed stakeholders of a possible change to the Hazardous Materials Regulations based on a petition for rulemaking submitted by the Attorney General of the State of New York regarding vapor pressure limits for crude oil. 
The ANPRM posed 39 questions on a 
wide variety of topics ranging from sampling and testing, proper classification, and numerous characteristics of crude oil relevant to its unique hazards. Specifically, PHMSA sought comments on whether there should be national vapor pressure standards for petroleum products and/or other Class 3 hazardous materials and, if so, recommendations for such thresholds. It was the intent of the ANPRM to obtain the views of those affected by the North Dakota Industrial Commission (NDIC) Order, as well as those who are likely to be impacted by the changes proposed in the petition P–1669 (as discussed in detail in the January 18, 2017 ANPRM), including those who are likely to benefit from, be adversely affected by, or potentially be subject to additional regulation. 
PHMSA sought comment on the 
ANPRM to assist in: 
1. Determining the best metric or 
combination of metrics (vapor pressure or other metric) for measuring and controlling fire and explosion risk in crude oil transport; 
2. Quantifying the improvement in 
safety if any, due to risk reduction from 
implementation of vapor pressure thresholds at varying levels; 
3. Identifying offerors’ compliance 
strategies and market impacts with Reid Vapor Pressure (RVP) standards at varying levels of stringency, and estimating their economic costs and environmental impacts; 
4. Identifying other regulations and 
industry practices, such as volatile organic compound emissions standards imposed through the Clean Air Act, or State regulations, or pipeline operator RVP standards, potentially affecting compliance strategies and costs, and safety benefits; 
5. Evaluating the extent to which use 
of DOT Specification 117 tank cars mitigates the risk of transporting crude oil; 
6. Comparing compliance costs of 
mitigation strategies with risk reduction from adoption of the petition; and 
7. Balancing the benefits and costs in 
setting the level of the chosen metric. 
II. Comment Period Extension 
PHMSA received an initial request 
from the American Petroleum Institute 
(API) to extend the comment period for the ANPRM by 30 days. API indicated in their request that industry needs extra time to obtain information on experiences with classification, testing, sampling, and packaging of unrefined petroleum products. Because of the number of questions posted, the technical nature of the questions, and the potentially broad implications to operations throughout the supply chain, API believes the opportunity for a thorough review before responding to PHMSA is crucial for any future rulemaking. Subsequent to the API request, PHMSA has received additional requests from other entities to extend the comment period. For instance, the North Dakota Petroleum Council also requests an extension; however, they have requested a 60-day extension. 
PHMSA provided an initial 60-day 
comment period to the ANPRM. However, due to our desire to collect meaningful input from a number of potentially affected stakeholders and to the demand by various entities, we agree with the requests to extend the comment period to allow further time for public input. Given the number and variety of requests, PHMSA is extending the comment period by 60 days.
