Colored Art Glass Manufacturing Facility Rules; Emission Control Device Requirements

(1) CAGMs must comply with the requirements in subsection (a) or (b), as applicable, for each emission control device used to comply with this rule.
(a) Tier 1 CAGMs must comply with one of the requirements in paragraphs (A), (B) or (C):
(A) Conduct a source test as required under section (3) and demonstrate that the emission control device does not emit particulate matter in excess of 0.005 grains per dry standard cubic foot as measured by EPA Method 5 or an equivalent method approved by DEQ.
(B) If the emission control system is a fabric filter (baghouse), install a bag leak detection system that meets the requirements of section (4).
(C) If the emission control system is a fabric filter (baghouse), install an afterfilter that meets the requirements of section (5).
(b) Tier 2 CAGMs must:
(A) Conduct a source test as required under section (3) and demonstrate that the emission control device does not emit particulate matter in excess of 0.005 grains per dry standard cubic foot as measured by EPA Method 5 or an equivalent method approved by DEQ; and
(B) If a fabric filter (baghouse) is used, install either a bag leak detection system that meets the requirements of section (4) or an afterfilter that meets the requirements of section (5).
(2) Emission control device requirements:
(a) A CAGM must obtain DEQ approval of the design of all emission control devices before installation, as provided in this rule.
(b) A CAGM must submit a Notice of Intent to Construct as required by OAR 340-210-0205 (Notice of Construction and Approval of Plans: Applicability) through 340-210-0250 (Notice of Construction and Approval of Plans: Approval to Operate) no later than 15 days before the date installation begins. If DEQ does not deny or approve the Notice of Intent to Construct within 10 days after receiving the Notice, the Notice will be deemed to be approved.
(c) Emission control devices may control emissions from more than one glassmaking furnace.
(d) Each emission control device must be equipped with the following monitoring equipment:
(A) An inlet temperature monitoring device;
(B) A differential pressure monitoring device if the emission control device is a baghouse; and
(C) Any other monitoring device or devices specified in DEQ’s approval of the Notice of Intent to Construct.
(e) Each emission control device must be equipped with inlet ducting that provides the following:
(A) Sufficient cooling of exhaust gases to no more than the maximum design inlet temperature under worst-case conditions; and
(B) Provision for inlet emissions testing, including sufficient duct diameter, sample ports, undisturbed flow conditions, and access for testing.
(f) Each emission control device must be equipped with outlet ducting that provides for outlet emissions testing, including sufficient duct diameter, sample ports, undisturbed flow conditions, and access for testing.
(g) After commencing operation of any emission control device, the CAGM must monitor the emission control device as required by OAR 340-245-9080 (Colored Art Glass Manufacturing Facility Rules; Emission Control Device Monitoring).
(3) If source testing is conducted under section (1), the CAGM must perform the following source testing on at least one emission control device.
(a) Within 60 days of commencing operation of the emission control devices, test control device outlet for particulate matter using DEQ Method 5 or equivalent method;
(b) The emission control device to be tested must be approved by DEQ;
(c) A source test plan must be submitted at least 30 days before conducting the source test; and
(d) The source test plan must be approved by DEQ before conducting the source test.
(4) If a bag leak detection system is installed under section (1), the requirements for the bag leak detection system are:
(a) The bag leak detection system must be installed and operational as soon as possible but not more than 90 days after the baghouse becomes operational or 90 days after the effective date of the rule, whichever is later.
(b) Each bag leak detection system must meet the specifications and requirements in paragraphs (A) through (H).
(A) The bag leak detection system must be certified by the manufacturer to be capable of detecting PM emissions at concentrations of 1 milligram per dry standard cubic meter (0.00044 grains per actual cubic foot) or less.
(B) The bag leak detection system sensor must provide output of relative PM loadings. The owner or operator must continuously record the output from the bag leak detection system using electronic or other means (e.g., using a strip chart recorder or a data logger).
(C) The bag leak detection system must be equipped with an alarm system that will sound when the system detects an increase in relative particulate loading over the alarm set point established according to paragraph (D), and the alarm must be located such that it can be heard by the appropriate plant personnel.
(D) In the initial adjustment of the bag leak detection system, the CAGM must establish, at a minimum, the baseline output by adjusting the sensitivity (range) and the averaging period of the device, the alarm set points, and the alarm delay time.
(E) Following initial adjustment, the CAGM may not adjust the averaging period, alarm set point, or alarm delay time without approval from DEQ except as provided in paragraph (F).
(F) Once per quarter, the CAGM may adjust the sensitivity of the bag leak detection system to account for seasonal effects, including temperature and humidity, according to the procedures identified in the site-specific monitoring plan required by OAR 340-224-9080(4).
(G) The CAGM must install the bag leak detection sensor downstream of the fabric filter.
(H) Where multiple bag leak detectors are required, the system’s instrumentation and alarm may be shared among detectors.
(5) If an afterfilter is installed under section (1), the requirements for the afterfilter are:
(a) The afterfilter must be installed and operational as soon as possible but not more than 120 days after the baghouse becomes operational or 120 days after the effective date of the rule, whichever is later;
(b) The afterfilter must filter the entire exhaust flow from the fabric filter (baghouse); and
(c) The afterfilter must be equipped with:
(A) HEPA filters that have a Minimum Efficiency Reporting Value of 17 (MERV 17) or higher per American National Standards Institute (ANSI) Standard 52.2; and
(B) A differential pressure monitoring device.
