Iowa Location Lindsay James Contact Service Lines Due DiligenceWater ResourcesAir Qualilty Project Summary Blackstone Environmental, Inc. supported the development of a new cement terminal in the Des Moines area by conducting a Phase I Environmental Site Assessment (ESA) and wetland delineation for a proposed site location and then preparing air quality permit applications for the proposed equipment. Phase I Environmental Site Assessment Blackstone conducted the Phase I ESA for a 15.09-acre agricultural property that was identified as a potential location for the cement terminal. The Phase I ESA assessed site conditions, both past, and present, for indications of recognized environmental conditions (RECs) at the Site prior to purchase. Land use in the area included recent light industrial development and agricultural/undeveloped properties. Aerial photos reviewed indicated that the site had been vacant or agricultural land since at least the late 1930s. Blackstone reviewed environmental database records, interviewed the current landowner, and conducted site reconnaissance, and did not identify indications of RECs associated with the historic use…

Kansas Location Austin Quick Contact Service Lines Air Quality Project Summary Blackstone prepared an air quality construction permit application for a natural gas liquids fractionation facility in Kansas. The project included updates to existing equipment within the fractionation train plus the addition of new equipment, including a boiler, a cooling tower, and piping & equipment components. Blackstone was provided the engineering plans for the proposed new and modified equipment and utilized that information, as well as ongoing discussions with the project engineering design team, to determine affected emission sources and to develop a permitting strategy. Services Provided Blackstone developed emissions calculations for the project, including baseline and past actual emissions to determine applicability of Prevention of Significant Deterioration (PSD) permitting, and potential emissions to determine applicability of state construction permitting. Several iterations of emissions calculations were prepared as the project design progressed. The past ten years of emissions inventories and production information was collected and reviewed to determine an appropriate baseline period. Since this project…
