# §63.11430. What are the standards?

- (a) If you use a pressure treatment process with any wood preservative containing chromium, arsenic, dioxins, or methylene chloride at a new or existing area source, the preservative must be applied to the wood product inside a retort or similarly enclosed vessel.
- (b) If you use a thermal treatment process with any wood preservative containing chromium, arsenic, dioxins, or methylene chloride at a new or existing area source, the preservative must be applied using process treatment tanks equipped with an air scavenging system to control emissions.
- (c) If you use any wood preservative containing chromium, arsenic, dioxins, or methylene chloride at a new or existing area source, you must prepare and operate according to a management practice plan to minimize air emissions from the preservative treatment of wood at a new or existing area source. You may use your standard operating procedures to meet the requirements for a management practice plan if it includes the minimum activities required for a management practice plan. The management practice plan must include, but is not limited to, the following activities:
  - (1) Minimize preservative usage;
  - (2) Maintain records on the type of treatment process and types and amounts of wood preservatives used at the facility;
  - (3) For the pressure treatment process, maintain charge records identifying pressure reading(s) inside the retorts (or similarly enclosed vessel);
  - (4) For the thermal treatment process, maintain records that the air scavenging system is in place and operated properly during the treatment process;
  - (5) Store treated wood product on drip pads or in a primary containment area to convey preservative drippage to a collection system until drippage has ceased;
  - (6) For the pressure treatment process, fully drain the retort to the extent practicable, prior to opening the retort door;
  - (7) Promptly collect any spills; and
  - (8) Perform relevant corrective actions or preventative measures in the event of a malfunction before resuming operations.
