# §63.2990. Can I conduct short-term experimental production runs that cause parameters to deviate from operating limits?


With the approval of the Administrator, you may conduct short-term experimental production runs during which your operating parameters deviate from the operating limits. Experimental runs may include, but are not limited to, runs using resin with a higher free-formaldehyde content than specified in the OMM plan, or using experimental pollution prevention techniques. To conduct a short-term experimental production run, you must complete the requirements in paragraphs [(a)](#a) and [(b)](#b) of this section.

- (a) **Prepare an application to the Administrator for approval to conduct the experimental production runs.** Your application must include the items listed in [paragraphs (a)(1) through (6)](#a-1..a-6) of this section.
  - (1) **The purpose of the experimental production run.**
  - (2) **Identification of the affected line.**
  - (3) An explanation of how the operating parameters will deviate from the previously approved ranges and limits.
  - (4) **The duration of the experimental production run.**
  - (5) **The date and time of the experimental production run.**
  - (6) **A description of any emission testing to be performed during the experimental production run.**
- (b) Submit the application to the Administrator for approval at least 30 days before you conduct the experimental production run.
- (c) If you conduct such experimental production runs without first receiving approval from the Administrator, then you must conduct a performance test under those same experimental production run conditions to show that you were in compliance with the formaldehyde emission limits in [§ 63.2983](/cfr/40/63.2983.md).
