If, by the expiration of the PMN review period, EPA does not notify you that your chemical will be subject to regulation, under Section 5, you are free to commence manufacture of the substance after the review period expires. During the PMN review period, the EPA Program Manager or other EPA personnel may contact you if EPA identifies concerns or seeks clarification of information provided in the PMN. The EPA Program Manager will also notify you before the review period expires if the review period will be extended under TSCA 5(c) or if regulatory action is being considered on the new 1-2 Section 1: General Program Information substance under TSCA 5(e) or 5(f). You may also refer to the New Chemicals Program website at www.epa.gov/oppt/newchems/dropstat.htm to obtain the status of PMNs or Low Volume Exemptions (LVEs) currently under review by EPA.
