Note: The Office of the Secretary of State has moved their content to a new server. Please use this link to access Texas Administrative Code Title 30 until TCEQ is able to update the linked content.
Equipment used with aqueous solutions for electrochemical surface coating or preparation is permitted by rule if operated under the specific conditions stated in Title 30, Texas Administrative Code (30 TAC), Section 106.375, and the general conditions stated in 30 TAC Section 106.4.
These are a few of the conditions stated in this permit by rule (PBR):
- For plating onto or stripping from any basis substrate, only these metals may be used:
- precious metals
- Chromic acid must not be used in any step that involves electrical current, air agitation, or any other factor that causes the chromic acid to bubble or mist.
- Systems for chemical milling or electrolytic metal recovery and reclamation are not covered by this PBR.
- Unless specific operating conditions are used to control or contain hydrochloric acid fumes, daily records must be kept as described below.
If your equipment meets the conditions of this PBR, our PBR Applicability Checklist, TCEQ Form - 10149, can help you determine whether your facility meets the general conditions of 30 TAC Section 106.4.
If your facility cannot comply with these conditions, see Types of New Source Review Authorizations for other options.
This permit by rule (PBR) does not require you to register or pay a fee.
If you claim this PBR for your facility, then under 30 TAC Section 106.8 your must keep records to identify the rules under which your facility is operating and demonstrate compliance for a rolling 12-month period. Be sure you keep at least these records:
- a copy of Section 106.4
- a copy of Section 106.264
- records documenting compliance with the above rules
In addition, if your equipment is not operated according to the conditions of this PBR with respect to hydrochloric acid, you must:
- Keep daily records of the maximum hydrochloric acid temperature and concentration for each tank.
- At least once each month, convert the daily recorded data to partial pressure.
- Maintain these records for a rolling 24-month period.
These records must be maintained on site and available on request for inspection by the TCEQ or any air pollution control program that has jurisdiction. If you have questions about the type of records you should keep, contact the Air Program in the TCEQ regional office that serves your county.
