In its memorandum “Evaluation of Competitive Harm from Disclosure of “Inputs to Equations” Data Elements Deferred to March 31, 2015” (refer to docket EPA-HQ-OAR-2010-0929), EPA identified these five “inputs to equations” data elements as production or raw material data, which were identified as having disclosure concerns. Based on these analysis results, EPA would have included these data elements in this table as part of its proposal to remove reporting of these data; however, EPA has excl uded the data elements from this table because §98.226(c) is a lready removed from Subpart V. §98.226(c) was inadvertently removed and reserved in conjunction with the 2010 technical corrections rulemaking (75 FR 79157, December 17, 2010); based on the results of its analysis , EPA is not taking any action to reinstate this provision.
