MSDS reporting stated in Sec. 370.30 is a one-time requirement. However, you must update the information in all of the following ways:
(a) Submit a revised MSDS after you discover significant new information concerning a hazardous chemical for which an MSDS was submitted.
(b) Submit an MSDS, or a list as described in Sec. 370.30(a), for any new hazardous chemical for which you become subject to these reporting requirements.
(c) Submit, as requested by the LEPC, an MSDS for any hazardous chemical present at your facility which you have not already submitted, as provided in Sec. 370.30(b).
