NSPS for Kraft Pulp Mills for which Construction, Reconstruction or Modification Commenced after May 23, 2103 (40 CFR part 60, subpart BBa) (Renewal)

The New Source Performance Standards (NSPS) for Kraft Pulp Mill Affected Sources for Which Construction, Reconstruction, or Modification Commenced After May 23, 2013 (40 CFR Part 60, Subpart BBa) were proposed on May 23, 2013, and promulgated on April 4, 2014. These regulations apply to emissions of particulate matter (PM) and total reduced sulfur (TRS) at recovery furnaces, smelt dissolving tanks (SDTs), lime kilns, digester systems, brown stock washer (BSW) systems, multiple effect evaporator systems and condensate stripper systems at kraft pulp mills that commenced construction, modification or reconstruction after May 23, 2013. At pulp mills, where kraft pulping is combined with neutral sulfite semi-chemical pulping, the provisions of this subpart are applicable when any portion of the material charged to an affected source is produced by the kraft pulping operation. This subpart includes provisions specifying that sources complying with the TRS standard for digester systems, BSW systems, evaporator systems and condensate stripper systems by venting to a control device must collect the gases in a closed-vent system subject to the provisions of 40 CFR Part 63, Subpart S. Facilities may be exempt from the TRS standard in the NSPS if the facility can demonstrate that TRS emissions from a brown stock washer cannot feasibly be controlled either technically or economically. 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 60, Subpart BBa. In general, all NSPS 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 NSPS.
