Public Notice: Request For Comments Proposed Air Quality Permit Approval Construction of Synthetic Minor Source Notice issued: August 3, 2012 Written comments due: 5 p.m., September 3, 2012 Permit Writer: Kathleen Paser Who is the applicant? Dakota Plains, Inc. Where is the facility located? Intersection of College Drive & Highway 23 - New Town, ND Latitude 47.977678N Longitude -102.476119W What is being proposed? The EPA proposes to issue an approval to construct a synthetic minor source of air pollutants to Dakota Plains, Inc. (Dakota Plains). Dakota Plains is requesting permission to a crude oil truck-to-rail trans-loading facility with 1 crude oil storage tanks (90,000 barrels total capacity), 5 truck-to-tank loading stations, and 13 tank-to-rail car loading stations. Permit number: SMNSR-T AT-000285-2012.001 Plant Site Emissions: The applicant has requested emission limitations that will limit the facility-wide emissions of volatile organic compounds (VOC) to levels below the thresholds that would require the applicant to obtain a Prevention of Significant Deterioration (PSD) pre-construction permit and a Title V Operating Permit. Potential uncontrolled emissions of VOC from the proposed construction are estimated at 1,034 tons per year (tpy). Potential uncontrolled emissions of all other regulated pollutants are estimated at concentrations below the levels that trigger minor source permitting requirements. Considering the EPA proposed requirements in the draft permit, potential controlled emissions of VOC from the proposed construction would be reduced to 97 tons per year. What are the special conditions of this permit? The permittee is required to use a vapor balance system, vapor collection system and combustion for control of VOC displaced during all loading/unloading operations. Additionally, the storage tank must be equipped with internal floating roof and all loading stations must use submerged filling. What are the effects on air quality? The EPA determined that dispersion modeling for the proposed project was not necessary, because emissions would be controlled by at least 98% and there are no identified air quality concerns within the external boundaries of the Fort Berthold Indian Reservation airshed. Where can I send comments? EPA accepts comments by mail, fax and e-mail.
