The NESHAP for Polyether Polyols Production (40 CFR Part 63, Subpart PPP) were proposed on September 4, 1997; promulgated on June 1, 1999; and amended on March 27, 2014. These regulations apply to both new and existing facilities that engage in the manufacture of polyether polyols (including polyether mono-ols) and emit hazardous air pollutants (HAPs). Owners or operators of polyether polyols production facilities to which this regulation applies must either choose one of the compliance options described in the rule or install and monitor a specific control system that reduces HAP emissions to the compliance level. Respondents are also subject to sections of 40 CFR Part 63, Subpart A. New facilities include those that commenced construction, modification, or reconstruction after the date of proposal. This information is being collected to assure compliance with 40 CFR Part 63, Subpart PPP. In general, all NESHAP standards require initial notifications, performance tests, and periodic reports by the owners/operators of the affected facilities. They are also required to maintain records of the occurrence and duration of any startup, shutdown, or malfunction in the operation of an affected facility, or any period during which the monitoring system is inoperative. These notifications, reports, and records are essential in determining compliance, and are required of all affected facilities subject to NESHAP.
