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.

(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.

(1) This rule applies to all flat wood manufacturing and surface finishing facilities that manufacture the following products:

(a) Printed interior panels made of hardwood plywood and thin particleboard;

(b) Natural finish hardwood plywood panels; or

(c) Hardboard paneling with Class II finishes.

(2) This rule does not apply 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 II finishes on hardboard panels, regardless of the number of coats applied.

(4) The emission limits in section (3) must be achieved by:

(a) The application of low solvent content coating technology; or

(b) An incineration system which oxidizes at least 90.0 percent of the nonmethane VOCs entering the incinerator (VOC measured as total combustible carbon) to carbon dioxide and water; or

(c) An equivalent means of VOC removal. The equivalent means must be approved in writing by DEQ. The time period used to determine equivalency may not exceed 24 hours.

(5) A capture system must be used in conjunction with the control devices in subsections (4)(b) and (c). The design and operation of a capture system must be consistent with good engineering practice and must provide for an overall emission reduction sufficient to meet the emission limitations in section (3).

(6) Compliance Demonstration:

(a) The owner or operator of a VOC source required to comply with this rule must demonstrate compliance by the methods of subsection (c), or an alternative method approved by DEQ;

(b) A person proposing to conduct a VOC emissions test must notify DEQ of the intent to test not less than 30 days before the proposed initiation of the tests so DEQ may observe the test;

(c) Test procedures in 40 CFR part 60, EPA Method 18, 24, or 25 must be used to determine compliance with section (3);

(d) DEQ may accept, instead of the coating analysis required by paragraph (c)(A), a certification by the coating manufacturer of the composition of the coating, if supported by actual batch formulation records. In the event of any inconsistency between a Method 18, 24, or 25 test and a facility's formulation data, the Method 18, 24, or 25 test will govern;

(e) If an add-on control device is used, continuous monitors of the following parameters must be installed, periodically calibrated, and operated at all times that the associated control device is operating:

(A) Exhaust gas temperature of all incinerators;

(B) Temperature rise across a catalytic incinerator bed; and

(C) Breakthrough of VOC on a carbon absorption unit.

NOTE: This rule is included in the State of Oregon Clean Air Act Implementation Plan that EQC adopted under OAR 340-200-0040.

Rotogravure and Flexographic Printing

(1) No owner or operator of a packaging rotogravure, publication rotogravure, flexographic or specialty printing facility, with the potential to emit before add on controls greater than 100 tons/year, employing ink containing solvent may operate, cause, allow or permit the operation of the press unless:

(a) The volatile fraction of ink, as it is applied to the substrate contains 25.0 percent by volume or less of organic solvent and 75 percent by volume or more of water;

(b) The ink as it is applied to the substrate, less water, contains 60.0 percent by volume or more nonvolatile material; or

(c) The owner or operator installs and operates:

(A) A carbon absorption system which reduces the volatile organic emissions from the capture system by at least 90.0 percent by weight;

(B) An incineration system which oxidizes at least 90.0 percent of the nonmethane VOCs, VOC measured as total combustible carbon, to carbon dioxide and water; or

(C) An alternative VOC pollution control device demonstrated to have at least a 90.0 percent removal efficiency, measured across the air pollution control device, that has been approved by DEQ.

(2) A capture system must be used in conjunction with the air pollution control devices in subsection (1)(c). The design and operation of a capture system must be consistent with good engineering practice, and must provide for a control efficiency in VOC emissions of at least:

(a) 75.0 percent where a publication rotogravure process is employed;

(b) 65.0 percent where a packaging rotogravure process is employed; or

(c) 60.0 percent where a flexographic printing process is employed.

(3) Compliance Demonstration:

(a) Upon request of DEQ, the owner or operator of a VOC source must demonstrate compliance by the methods of this section or an alternative method approved by DEQ. All tests must be made by, or under the direction of, a person qualified by training and/or experience in the field of air pollution testing;

(b) A person proposing to conduct a VOC emissions test must notify DEQ of the intent to test not less than 30 days before the proposed initiation of the tests so DEQ may observe the test. The notification must contain the information required by, and be in a format approved by, DEQ;

(c) Test procedures to determine compliance with this rule must be approved by DEQ and consistent with:

(A) EPA Test Method 18, 24, or 25, 40 CFR part 60; or California Method ST-7; or

(B) DEQ may accept, instead of ink-solvent analysis, a certification by the ink manufacturer of the composition of the ink-solvent, if supported by actual batch formulation records. In the event of any inconsistency between an EPA Method test and a facility's formulation data, the EPA Method test will govern.

(d) If an add-on control device is used, continuous monitors of the following parameters must be installed, periodically calibrated, and operated at all times that the associated control device is operating:

(A) Exhaust gas temperature of all incinerators;

(B) Breakthrough of VOC on a carbon adsorption unit; and

(C) Temperature rise across a catalytic incinerator bed.
