(b) Submit an MSDS (or SDS), or a list as described in § 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 (or SDS) for any hazardous chemical present at your facility which you have not already submitted, as provided in § 370.30(b).
