Information Collection Request Submitted to OMB for Review and
Approval; Comment Request; NSPS for Bulk Gasoline Terminals (Renewal)

AGENCY: Environmental Protection Agency (EPA).

ACTION: Notice.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency has submitted an
information collection request (ICR), ``NSPS for Bulk Gasoline
Terminals (40 CFR part 60, subpart XX) (Renewal)'' (EPA ICR No.
0664.11, OMB Control No. 2060-0006) to the Office of Management and
Budget (OMB) for review and approval in accordance with the Paperwork
Reduction Act (44 U.S.C. 3501 et seq.). This is a proposed extension of
the ICR, which is currently approved through January 31, 2015. Public
comments were previously requested via the Federal Register (79 FR
30117) on May 27, 2014 during a 60-day comment period. This notice
allows for an additional 30 days for public comments. A fuller
description of the ICR is given below, including its estimated burden
and cost to the public. 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.

DATES: Additional comments may be submitted on or before February 19,
2015.

ADDRESSES: Submit your comments, referencing Docket ID Number EPA-HQ-
OECA-2014-0027, to (1) EPA online using www.regulations.gov (our
preferred method), by email to<EMAIL_ADDRESS>or by mail to: EPA
Docket Center, Environmental Protection Agency, Mail Code 28221T, 1200
Pennsylvania Ave. NW., Washington, DC 20460, and (2) OMB via email to
<EMAIL_ADDRESS>Address comments to OMB Desk Officer for
EPA.
    EPA's policy is that all comments received will be included in the
public docket without change including any personal information

    Abstract: This rule applies to affected facilities at bulk gasoline
terminals which have a throughput greater than 75,700 liters per day,
delivering liquid product into gasoline tank trucks. The affected
facility includes the loading arms, pumps, meters, shutoff valves,
relief valves, and other piping and valves necessary to fill delivery
tank trucks. New facilities include those that commenced construction,
modification, or reconstruction after the date of proposal. The
standard sets initial notification, initial performance test, and
ongoing recordkeeping requirements. The required monthly leak detection
records are used to determine periods of excess emissions, identify
problems at the facility, verify operation/maintenance procedures and
for compliance determinations. This information is collected to assure
compliance with 40 CFR part 60, subpart XX.
    Form Numbers: None.
    Respondents/affected entities: Bulk gasoline terminals.
    Respondent's obligation to respond: Mandatory (40 CFR part 60,
Subpart XX).
    Estimated number of respondents: 40 (total).
    Frequency of response: Initially.
    Total estimated burden: 13,165 hours (per year). Burden is defined
at 5 CFR 1320.3(b).
    Total estimated cost: $1,288,907 (per year), includes $0 annualized
capital or operation & maintenance costs.
    Changes in the Estimates: There is no change in the labor hours in
the total estimated respondent burden compared with the ICR currently
approved by OMB.

Comment Info: =================

General Comment:Mr Zeller,

I am writing as an individual consumer to request an extension of the comment period for the Food and Drug Administration's ("FDA") Proposed Rule Deeming Tobacco Products to be Subject to the Federal Food, Drug, and Cosmetic Act, as amended by the Family Smoking and Prevention and Tobacco Control Act (the "Proposed Rule") published at 79 Fed. Reg. 23,142 and Federal Register No. 2014-09491. On behalf of myself, I am requesting that the comment period for the Proposed Rule be extended by the FDA for an additional 105 days, from its current 75-day period, to 180 days.

FDA, which took more than three years to issue its 241-page Proposed Regulation (and accompanying 81-page regulatory impact analysis), has given us a mere 75 days to comment. While responding in that timeframe is challenging under any circumstances, the FDA has also posed, by our count, 99 requests for information about THR products (this does not include repeat questions or questions specifically pertaining to cigars). Given the length of time FDA has taken to release the proposed regulations, the massive amount of information FDA is requesting, the length of the document itself, and the devastating impact these regulations will have on a product that is estimated to be approximately 99% less hazardous than combustibles, the 75-day comment period is grossly inadequate. PLEASE DO ADDITIONAL RESEARCH BEFORE MAKING ANY RULING.

http://onvaping.com/the-ultimate-list-of-studies-on-e-cigarettes-and-their-safety/

I feel very strongly about e-cigarettes as an alternative to combustible cigarettes. Quite simply, I firmly believe that they saved my life. I wish to provide you with my personal story, as well as science- and evidence-based responses to your questions so that you can take my comment into account. I realize that the FDA has the authority under 21 CFR 10.40 to extend this time frame and that the FDA has exercised this authority on numerous occasions in the past. I would therefore ask that you do so here, so that all stakeholders have the opportunity to provide their comments on this proposed regulation.

I appreciate your consideration of my request and am happy to discuss this issue with you further.
