General Non-Categorical Requirements
(1) All existing sources operating prior
to November 15, 1990, located inside the areas cited in OAR 340-232-0020(1)(a) or
(1)(c), containing emissions units or devices for which no categorical RACT requirements
exist and which have potential emissions before add-on controls of over 100 tons
per year of VOC from aggregated, non-regulated emission units, must have RACT requirements
developed on a case-by-case basis by DEQ. Sources that have complied with NSR requirements
per OAR 340 division 224 and are subject to Best Available Control Technology (BACT)
or Lowest Achievable Emission Rate (LAER) requirements are presumed to have met
RACT requirements. A source may request RACT not be applied by demonstrating to
DEQ that its potential emissions before add-on controls are less than 100 tons per
year. Once a source becomes subject to RACT requirements under this section, it
will continue to be subject to RACT, unless VOC emissions fall less than 100 tons
per year and the source requests that RACT be removed, by demonstrating to DEQ that
their potential VOC emissions before add-on controls are below 100 tons per year.
(2) Within 3 months of written
notification by DEQ of the applicability of this rule, or, for good cause shown,
up to an additional three months as approved by DEQ, the source must submit to DEQ
a complete analysis of RACT for each category of emissions unit at the source, taking
into account technical and economic feasibility of available control technology,
and the emission reductions each technology would provide. This analysis does not
need to include any emissions units subject to a specific categorical RACT requirement
under this division. These RACT requirements approved by DEQ will be incorporated
in the source's Air Contaminant Discharge Permit, and will be effective upon approval
by EPA as a source specific SIP revision. The source must comply with the applicable
RACT requirements beginning one year from the date of notification by DEQ of EPA
approval.
(3) Failure by a source to
submit a RACT analysis required by section (2) does not excuse the source from the
obligation to comply with a RACT determination established by DEQ.
NOTE: This rule is included in the
State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.

Bulk Gasoline Plants Including Transfer
of Gasoline
(1) No person may transfer or allow
the transfer of gasoline to or from a bulk gasoline plant unless:
(a) Each stationary storage
tank uses submerged fill when transferring gasoline; and
(b) The displaced vapors
from filling each tank are prevented from being released to the atmosphere through
use of a vapor tight vapor balance system. All equipment associated with the vapor
balance system must be maintained to be vapor tight and in good working order.
(2) Each stationary gasoline
storage tank may release vapor to the atmosphere through a pressure relief valve
set to release at the highest possible pressure in accordance with state or local
fire codes, or the National Fire Prevention Association guidelines and no less than
3.4 kPa (0.50 psi).
(3) Gasoline must be handled
in a manner to prevent spillage, discharging into sewers, storage in open containers,
or handled in any other manner that would result in evaporation. If more than five
gallons are spilled, the operator must report the spillage in accordance with OAR
340-214-0300 to 340-214-0350.

Loading Gasoline and Volatile Organic
Liquids onto Marine Tank Vessels
(1) Applicability. This rule applies
to loading events at any location within the Portland ozone air quality maintenance
area when a liquid product identified in subsection (a) or (b), as applicable, is
placed into a marine tank vessel cargo tank; or where any liquid is placed into
a marine tank vessel cargo tank that had previously held a liquid product identified
in subsection (a) or (b), as applicable. The owner or operator of each marine terminal
and marine tank vessel is responsible for and must comply with this rule.
(a) Prior to July 1, 2018,
liquid product means gasoline;
(b) On and after July 1,
2018, liquid product means all of the following:
(A) Gasoline;
(B) Any other volatile organic
liquid with a Reid vapor pressure of 27.6 kPa (4.0 psi) or more; and
(C) Any other organic liquid
if the liquid is purposely heated, the liquid temperature is 110 degrees Fahrenheit
or more at the time of loading, and the liquid has a Reid vapor pressure of 20.7
kPa (3.0 psi) or more.
(2) Exemptions. The following
activities are exempt from the marine vapor control emission limits of this rule:
(a) Marine vessel bunkering;
(b) Lightering when neither
vessel is berthed at a marine terminal dock,
(c) Loading when both of
the following conditions are met:
(A) The vessel has been gas
freed (regardless of the prior cargo), and
(B) When loading any products
other than a liquid product identified in subsection (1)(a) or (1)(b), as applicable;
and
(d) Loading organic liquids
that are stored in pressurized tanks, such as but not limited to liquefied natural
gas, liquefied petroleum gas, butane and propane.
(3) Vapor Collection System.
The owner or operator of a marine terminal subject to this rule must equip each
loading berth with a vapor collection system that is designed to collect all displaced
VOC vapors during the loading of marine tank vessels. The owner or operator of a
marine tank vessel subject to this rule must equip each marine tank vessel with
a vapor collection system that is designed to collect all displaced VOC vapors during
the loading of marine tank vessels. The collection system must be designed such
that all displaced VOC vapors collected during any loading event are vented only
to the control device.
(4) Marine Vapor Control
Emission Limits. Vapors that are displaced and collected during marine tank vessel
loading events must be reduced from the uncontrolled condition by at least 95 percent
by weight, as determined by EPA Method 25 or other methods approved under OAR 340-212-0140,
or limited to 5.7 grams per cubic meter (2 pounds per 1000 barrels) of liquid loaded.
(5) Operating Practice and
Maintenance.
(a) All hatches, pressure
relief valves, connections, gauging ports and vents associated with the loading
of liquid product identified in subsection (1)(a) or (1)(b), as applicable, into
marine tank vessels must be maintained to be leak free and vapor tight.
(b) The owner or operator
of any marine tank vessel must certify to DEQ that the vessel is leak free, vapor
tight, and in good working order based on an annual inspection using EPA Method
21 or other method approved under OAR 340-212-0140.
(c) Gaseous leaks must be
detected using EPA Method 21 or other methods approved under OAR 340-212-0140.
(d) Loading must cease anytime
gas or liquid leaks are detected. Loading may continue only after leaks are repaired
or if documentation is provided to DEQ that the repair of leaking components is
technically infeasible without dry-docking the vessel or cannot otherwise be undertaken
safely. Subsequent loading events involving the leaking components are prohibited
until the leak is repaired. Any liquid or gaseous leak detected by DEQ staff is
a violation of this rule.
(6) Monitoring and recordkeeping.
Marine terminal operators must maintain operating records for at least five years
of each loading event at their terminal. Marine tank vessel owners and operators
are responsible for maintaining operating records for at least five years for all
loading events involving each of their vessels. Records must be made available to
DEQ upon request. These records must include but are not limited to:
(a) The location of each
loading event.
(b) The date of arrival and
departure of the vessel.
(c) The name, registry and
legal owner of each marine tank vessel participating in the loading event.
(d) The type and amount of
liquid product loaded into the marine tank vessel.
(e) The prior cargo carried
by the marine tank vessel. If the marine tank vessel has been gas freed, then the
prior cargo can be recorded as gas freed.
(f) The description of any
gaseous or liquid leak, date and time of leak detection, leak repair action taken
and screening level after completion of the leak repair.
(7) Lightering exempted from
controls by subsection (2)(b) must be curtailed from 2:00 a.m. until 2:00 p.m. when
DEQ declares a Clean Air Action day. If DEQ declares a second clean air action day
before 2:00 p.m. of the first curtailment period, then such uncontrolled lightering
must be curtailed for an additional 24 hours until 2:00 p.m. on the second day.
If a third clean air action day in a row is declared, then uncontrolled lightering
is permissible for a 12-hour period starting at 2 p.m. on the second clean air action
day and ending at 2 a.m. on the third clean air action day. Uncontrolled lightering
must be curtailed from 2 a.m. until 2 p.m. on the third clean air action day. If
DEQ continues to declare clean air action days consecutively after the third day,
the curtailment and loading pattern used for the third clean air action day will
apply.
(8) Safety/Emergency Operations.
Nothing in this rule is intended to:
(a) Require any act or omission
that would be in violation of any regulation or other requirement of the United
States Coast Guard; or
(b) Prevent any act that
is necessary to secure the safety of a vessel or the safety of passengers or crew.

to the manufacture of exterior siding, tileboard, particleboard used as a furniture
component, or paper or plastic laminates on wood or wood-derived substrates.
(3) No owner or operator
of a flat wood manufacturing facility subject to this rule may emit VOCs from a
coating application system in excess of:
(a) 2.9 kilograms per 100
square meters of coated finished product (6.0 pounds/1,000 square feet) from printed
interior panels, regardless of the number of coats applied;
(b) 5.8 kilograms per 100
square meters of coated finished product (12.0 pounds/1,000 square feet) from natural
finish hardwood plywood panels, regardless of the number of coats applied; and
(c) 4.8 kilograms per 100
square meters of coated finished product (10.0 pounds/1,000 square feet) from Class
