25 Pa. Code § 129.81 - Organic liquid cargo vessel loading and ballasting
The following provisions apply in the counties of Delaware and Philadelphia:
(1) A person
may not cause or permit the loading of gasoline into an organic liquid cargo
vessel unless the following exist:
(i) The
VOC vapors displaced by the loading operation are processed through a vapor
recovery or destruction device operated to reduce the VOCs by at least 90% by
weight.
(ii) The vapor collection
and transport system employed to carry VOCs to the vapor control system is
maintained and operated so that it prevents the following:
(A) A reading equal to or greater than 100%
of the lower explosive limit (LEL), measured as propane, at 1 inch (2.5
centimeters) from all points on the perimeter of a potential leak source when
measured by the method referenced in §
139.14 (relating to emissions of
VOCs) during loading operations.
(B) Avoidable liquid leaks during loading
operations.
(C) Visually or audibly
detectable leaks in the organic liquid cargo vessel's cargo tanks, hatch
covers, storage tanks pressure/vacuum relief values and associated vapor and
liquid lines during loading.
(iii) The pressure and vacuum relief valves
on the liquid cargo vessel are set to release at no less than 0.7 psig (4.8
kilopascals) of pressure or 0.3 psig (2.1 kilopascals) of vacuum or the highest
allowable pressure and vacuum as specified in State or local fire codes, the
National Fire Prevention Association guidelines or other National consensus
standards acceptable to the Department.
(2) Except as provided in paragraph (4), a
person may not cause or permit the emission of VOCs from the ballasting of an
organic liquid cargo vessel containing crude oil or gasoline unless the
emissions are processed through a vapor recovery or destruction device operated
so as to reduce the VOCs by at least 90% by weight.
(3) Compliance with this section shall be
achieved in accordance with the following:
(i)
Installation of the piping, pressure relief valves and other devices necessary
to collect and transport VOCs from affected organic liquid vessel cargo
compartments to the required VOC vapor recovery/destruction system shall be
completed by September 28, 1996.
(ii) Installation of vapor recovery
devices/destruction devices at marine terminals shall be completed by September
28, 1994.
(iii) Installation of
vessel mounted vapor recovery or destruction devices shall be completed by
September 28, 1996.
(4)
Other provisions of this section notwithstanding, the Department may allow a
facility to implement permanent and enforceable measures, including
recordkeeping and reporting requirements, which are approved by the EPA to
reduce the emission of VOCs from ballasting of an organic liquid cargo vessel
containing crude oil or gasoline as follows:
(i) By September 28, 1992, a minimum of 40%
of the total volume of receipts of crude oil and gasoline during a specified
period shall be delivered to the facility in vessels which do not ballast, such
as barges, or in vessels which do not emit VOCs when ballasted, such as tankers
using segregated ballast tanks.
(ii) By September 28, 1996, a minimum of 65%
of the total volume of receipts of crude oil and gasoline during a specified
period shall be delivered to the facility in vessels which do not ballast, such
as barges, or in vessels which do not emit VOCs when ballasted, such as tankers
using segregated ballast tanks.
(iii) By January 1, 2003, a minimum of 90% of
the total volume of receipts of crude oil and gasoline during a specified
period shall be delivered to the facility in vessels which do not ballast, such
as barges, or in vessels which do not emit VOCs when ballasted, such as tankers
using segregated ballast tanks.
(iv) By January 1, 2010, 98% of the total
volume of receipts of crude oil and gasoline during a specified period shall be
delivered to the facility in vessels which do not ballast, such as barges, or
in vessels which do not emit VOCs when ballasted, such as tankers using
segregated ballast tanks.
(5) Compliance with paragraphs (2)-(4) may
also be achieved by meeting the requirements for equivalency in §
129.51(a)
(relating to general).
