unloading tank truck or trailer and a receiving stationary storage tank
such that vapors displaced from the receiving stationary storage tank
are transferred to the tank truck or trailer being unloaded.

(7)	"Outgoing vapor balance system" means a combination of pipes or

detector using the test procedure described in Rule .0940 of this
Section.

(7)	"Liquid balancing" means a process used to degas floating roof
gasoline storage tanks with a liquid whose vapor pressure is below 1.52
psia. This is done by removing as much gasoline as possible without
landing the roof on its internal supports, pumping in the replacement
fluid, allowing mixing, remove as much mixture as possible without
landing the roof, and repeating these steps until the vapor pressure of
the mixture is below 1.52 psia.

(8)	"Liquid displacement" means a process by which gasoline vapors,
remaining in an empty tank, are displaced by a liquid with a vapor

manufacturer and maintain in his records a pre-installation
certification stating the vapor control efficiency of the system in use;

(2)	Displaced vapors and gases are vented only to the vapor control
system or to a flare;

terminal that existed before December 1, 1992, an increase in benzene
emissions results such that:

(1)	emissions of volatile organic compounds increase by more than 25
tons cumulative at any time during the five years following
modifications; and

(2)	annual emissions of benzene from the cluster where the bulk gasoline
terminal is located (including the pipeline and marketing terminals
served by the pipeline) exceed benzene emissions from that cluster based
upon calendar year 1991 gasoline throughput and application of the
requirements of this Subchapter,

shall be offset within the cluster by reduction in benzene emissions
beyond that otherwise achieved from compliance with this Rule, in the

gasoline or the equivalent of gasoline vapor and gasoline liquid are
exempted from the degassing requirements if gasoline vapors are vented
for at least 24-hours. Documentation of degassing external or internal
floating roof tanks shall be made according to 15A NCAC 02D .0903.

If no leaks are found, the owner or operator shall record that no leaks
were found. If a leak is found, the owner or operator shall record the
information specified in Paragraph( (p) of this Rule. The owner or
operator shall repair all leaks found according to Paragraph (q) of this
Rule.

(3)	the corrective action taken,

(4)	the date when corrective action was completed, and

(5)	any other information that the terminal deems necessary to
demonstrate compliance.

(q)  The owner or operator of a bulk gasoline terminal shall repair all
leaks as follows:

(1)	The vapor collection hose that connects to the tank truck or trailer
shall be repaired or replaced before another tank truck or trailer is
loaded at that rack after a leak has been detected originating with the
terminal’s equipment rather than from the gasoline tank truck or
trailer.

(2)	All other leaks shall be repaired as expeditiously as possible but
no later than 15 days from their detection. If more than 15 days are
required to make the repair, the reasons that the repair cannot be made
shall be documented, and the leaking equipment shall not be used after

asphalt course. It also reduces the necessity of maintaining an
untreated base course prior to placing the asphalt pavement.

(b)  This Regulation applies to the manufacture and use of cutback
asphalts for the purpose of paving or maintaining roads, highways,
streets, parking lots, driveways, curbs, sidewalks, airfields (runways,

(c)  Cutback asphalt shall not be manufactured, mixed, stored, used, or
applied except where:

application at ambient temperatures less than 50F, as measured at the
nearest National Weather Service Field Office or Federal Aviation

this Section apply and which are located at a facility where the total
potential emissions of volatile organic compounds from all stationary
sources at the facility are 100 tons per year or more; and

(2)	sources covered under Rule .0953 or .0954 of this Section.

(c)  If the owner or operator of any source of volatile organic
compounds subject to the requirements of this Section, can demonstrate
that compliance with rules in this Section would be technologically or
economically infeasible, he may petition the Director to allow the use
of alternative operational or equipment controls for the reduction of
volatile organic compound emissions.  Petition shall be made for each
source to the Director.

(d)  The petition shall contain:

(1)	the name and address of the company and the name and telephone
number of a company officer over whose signature the petition is
submitted;

(2)	a description of all operations conducted at the location to which
the petition applies and the purpose that the volatile organic compound
emitting equipment serves within the operations;

(3)	reference to the specific operational and equipment controls under
the rules of this Section for which alternative operational or equipment
controls are proposed;

(4)	a detailed description of the proposed alternative operational or
equipment controls, the magnitude of volatile organic compound emission
reduction that will be achieved, and the quantity and composition of
volatile organic compounds that will be emitted if the alternative
operational or equipment controls are instituted;

(5)	a plan, which will be instituted in addition to the proposed
alternative operational or equipment controls, to reduce, where
technologically and economically feasible, volatile organic compound
emissions from other source operations at the facility, further than
that required under the rules of this Section, if these sources exist at
the facility, such that aggregate volatile organic compound emissions
from the facility will in no case be greater through application of the
alternative control than would be allowed through conformance with the
rules of this Section;

(6)	a schedule for the installation or institution of the alternative
operational or equipment controls in conformance with Rule .0909 of this
Section, as applicable; and

(7)	certification that emissions of all other air contaminants from the
subject source are in compliance with all applicable local, state and
federal laws and regulations.

The petition may include a copy of the permit application and need not
duplicate information in the permit application.

(e)  The Director shall approve a petition for alternative control if:

(1)	The petition is submitted in accordance with Paragraph (d) of this
Rule;

(2)	The Director determines that the petitioner cannot comply with the
rules in question because of technological or economical infeasibility

(3)	All other air contaminant emissions from the facility are in
compliance with, or under a schedule for compliance as expeditiously as
practicable with, all applicable local, state, and federal regulations;
and

(4)	The petition contains a schedule for achieving and maintaining
reduction of volatile organic compound emissions to the maximum extent
feasible and as expeditiously as practicable.

(f)  When controls different from those specified in the appropriate
emission standards in this Section are approved by the Director, the
permit shall contain a condition stating such controls.

(a)  Applicability.  This Rule applies to any facility located in
Davidson, Durham, Forsyth, Gaston, Guilford, Mecklenburg, or Wake
counties or the Dutchville Township in Granville county or that portion
of Davie County that is bounded by the Yadkin River, Dutchman's Creek,
NC Highway 801, Fulton Creek and back to the Yadkin River:

(1)	that is built after June 30, 1994, or

(2)	whose tanks are replaced or removed for upgrades or repairs after
June 30, 1994.

When a new tank is added, the new tank shall comply with this Rule.

(b)  Exemptions. The burden of proof of eligibility for exemption from
this Rule is on the owner or operator of the facility. Persons seeking
an exemption from this Rule shall maintain records of throughput and
