ECLSS Universal Waste Management System (UWMS) Metal Materials Compatibility Study - Elgiloy: Electrochemical and Crevice Corrosion Evaluation

Electrochemical evaluations were conducted on samples of Elgiloy in support of the materials compatibility program for the Environmental Control and Life Support System (ECLSS). Results were compared alongside three previously tested metals: Titanium 6Al-4V, Inconel 625, and Hastelloy C276. Titanium exhibited the best results of all the metals, indicating superior corrosive nobility and galvanic protection properties. Elgiloy demonstrated anti-corrosion behavior which appeared to be superior to the two nickel-chromium alloys. For this current effort, the results have clearly shown that Elgiloy possesses excellent corrosion protection properties and is galvanically compatible with the other three metals in the subject test media.

Pedestal Hazard Abatement and Soil Removal Construction Completion Report for Launch Complex 34, Solid Waste Management Unit CC054, Cape Canaveral Space Force Station, Florida

This Construction Completion Report summarizes the activities associated with implementation of an interim measure (IM) for hazard abatement of the Launch Pedestal and soil removal at Launch Complex 34 (LC34), Cape Canaveral Space Force Station, Florida. The purpose of the hazard abatement IM was to mitigate any continuing source of contamination associated with residual paint on the Launch Pedestal that contained polychlorinated biphenyls (PCBs). Sampling determined that residual PCB concerns were limited to the steel elements on the top-side of the Pedestal, which included the torus ring, feed pipe, down pipes, pipe straps and shields, remaining steel cover plates and bolts, and railing support steel. The IM also mitigated the potential spread of contamination to surrounding areas by removing fallen metal fragments from the concrete launch pad, as well as soil from trenches on the launch pad where PCB-containing paint chips may have accumulated prior to or during Pedestal hazard abatement activities.

Request for Discontinuation of Long-Term Monitoring Orsino Storage Yard Solid Waste Management Unit 004 Kennedy Space Center, Florida

This report presents the site history, groundwater sampling results, and recommendations from the 2021 Industrial Area (IA) LTM activities at ORSY. ORSY has been used as a staging facility for electrical equipment since 1966 (EG&G 1991). Initial investigations conducted between 1986 and 1992 focused on polychlorinated biphenyls (PCBs) in soil. A series of soil excavation interim measures (IMs) were conducted to remove soils containing total PCB concentrations of greater than 25 milligrams per kilogram (mg/kg). A Resource Conservation and Recovery Act (RCRA) Facility Investigation (RFI) was completed in several phases at ORSY from 1998 through 2005, with PCBs in soil and volatile organic compounds (VOCs) in groundwater identified as contaminants of concern.

Converter/Compressor Building Solid Waste Management Unit (SWMU) #89 Monitoring Well 21 Area Interim Measure Work Plan

This Work Plan details the approach and design for the Interim Measure (IM) to remediate groundwater within the MW21 Area where VOC concentrations exceed Florida Department of Environmental Protection Natural Attenuation Default Concentrations. The IM includes in-situ bioremediation via injection of emulsified vegetable oil (EVO) and emulsified zero-valent iron (EZVI). The in-situ bioremediation technology consists of injecting an electron donor substrate into the subsurface to promote microbial breakdown of VOCs. The EVO injections for this IM are designed based on the use of Provectus ERD-CH4, which is a vegetable oil/carbon substrate mixture. The EZVI injections for this IM are designed based on the use of Provectus EZVI-CH4. The IM treatment layout consists of nine injection locations of EVO at approximately 10-foot radius of influence (ROI) and three injections locations of EZVI at approximately 6-foot ROI. The injection method will be direct push using a DPT rig. The overall injection depths range from 7 to 17 ft bls. The 7 ft bls top depth is designed to be 2 ft below the water table to prevent substrates from reaching the top of the water table. Injections are planned to be implemented using 2 ft intervals and will take place using a bottom-up approach to 2 ft below the water table. This work plan further describes the IM design, injection calculations, performance monitoring plan, and provides an injection layout. Revision 1 of this Work Plan includes quarterly performance sampling during Year 1 in accordance with F.A.C. 62-780. These changes are reflected in Section 7 and Table 2 of the Work Plan.

Monitoring Well Abandonment Completion Report for KARS Park1, Mobil Service Station, and Hypergol Maintenance Material North Solid Waste Management Units: 084, 093, and 090

The intended purpose of the Monitoring Well Abandonment project is to support the Kennedy Space Center (KSC) Environmental Remediation Department’s Resource Conservation and Recovery Act Program by abandoning monitoring wells throughout KSC that have been identified and prioritized as locations that no longer serve usefulness to program. The monitoring wells were abandoned in accordance with the Brevard County Health Departments and St. Johns River Water Management Districts rules and guidelines.
