SUPPLEMENTARY INFORMATION:

Decision To Be Made

This DEIS informs NASA decision makers, regulating agencies, and the public of the potential environmental consequences of the proposed demolition of SSFL buildings and structures and the proposed technologies for groundwater and soil remediation, as implemented through the Proposed Action. This DEIS analyzes a range of remedial technologies that might be implemented to achieve the proposed groundwater and soil remediation goals. NASA will use the DEIS analysis to consider the potential environmental, economic, and social impacts from the Proposed Action. On the basis of the DEIS findings, NASA will issue a Record of Decision (ROD) documenting the findings. The ROD will further identify which buildings will be demolished to support disposition of the property, and which remedial technology(ies) would will be applied to meet the soil cleanup and groundwater quality goals.

The purpose of this notice is to apprise interested agencies, organizations, tribal governments, and individuals of the availability of the DEIS and to invite comments on the document. NASA will hold public meetings as part of the DEIS review process.

Site Description

The SSFL site is 2,850 acres located in Ventura County, California, approximately seven miles northwest of Canoga Park and approximately 30 miles northwest of downtown Los Angeles. SSFL is composed of four areas known as Areas I, II, III, and IV and two unnumbered areas known as the “undeveloped land.” NASA administers 41.7 acres within Area I and all 409.5 acres of Area II. The Boeing Company manages the remaining 2,398.8 acres within Areas I, III, and IV, and the two undeveloped areas.

Since the mid-1950s, when the two federally owned areas were owned by the U.S. Air Force, this site has been used for developing and testing rocket engines. Four test stand complexes were constructed in Area II between 1954 and 1957 named Alfa, Bravo, Coca, and Delta. Area II and the LOX Plant portion of Area I were acquired by NASA from the U.S. Air Force in the 1970s. These test stands and related ancillary structures have been found to have historical significance based on the historic importance of the engine testing and the engineering and design of the structures.

The NASA-administered areas of SSFL also contain cultural resources not related to rocket development. SSFL is located near the crest of the Simi Hills that are part of the Santa Monica Mountains running east-west across Southern California. The diverse terrain consists of ridges, canyons, and sandstone rock outcrops. The region was occupied by Native Americans from the earliest Chumash, Tongva, and Tataviam cultures. NASA has conducted several previous surveys to locate archaeological and architectural resources within its portion of the SSFL. As a result, NASA has identified one historic property, the Burro Flats Painted Cave, that is listed on the National Register of Historic Places Start Printed Page 47008(NRHP), as well as multiple buildings and structures that are either individually eligible for listing on the NRHP or are elements of NRHP-eligible historic districts containing multiple architectural resources.

Previous environmental sampling on the NASA-administered property indicates that metals, dioxins, polychlorinated biphenyls (PCBs), volatile organics, and semivolatile organics are present in the soils and upper groundwater (known as the Surficial Media Operable Unit). Volatile organics, metals, and semivolatile organics are also present in the deeper groundwater (known as the Chatsworth Formation Operable Unit).

Environmental Commitments and Associated Environmental Review

Rocket engine testing has been discontinued at these sites and the property has been excessed to the General Services Administration (GSA). GSA has conditionally accepted the Report of Excess pending (i) NASA's certification that all action necessary to protect human health and the environment with respect to hazardous substances on the property has been taken or receipt of EPA's written concurrence that an approved and installed remedial design is operating properly and successfully; OR (ii) the Governor's concurrence in the suitability of the property for transfer per CERCLA Section 120(h)(3)(C).

In 2007, a Consent Order among NASA, Boeing, the Department of Energy (DOE), and Department of Toxic Substances Control (DTSC) for the State of California was signed addressing the demolition of certain infrastructure and environmental cleanup of SSFL. NASA entered into an Administrative Order on Consent (AOC) for Remedial Action with DTSC on December 6, 2010, “to further define and make more specific NASA's obligations with respect to the cleanup of soils at the Site.” Based on the 2010 AOC, NASA is required to complete a federal environmental review pursuant to NEPA. “An EIS is being prepared by NASA to include demolition of site infrastructure and soil cleanup (pursuant to the AOC), and groundwater remediation within Area II and a portion of Area I (Liquid Oxygen [LOX] Plant) of SSFL (pursuant to the 2007 Consent Order).” As part of the environmental review process, certain studies have been or are being completed, to characterize the existing conditions and to inform the analysis and consultation. These include surveys for wildlife, critical habitat, rare plants, wetlands, and archaeological and cultural resources. The findings of these studies are being incorporated into the DEIS.

Alternatives

To prepare SSFL for disposition, NASA describes the demolition of SSFL structures and cleanup of the site necessary to meet only the strictest cleanup alternative, as dictated by the 2007 Consent Order and the 2010 AOC requirements, and the “No Action” alternative required by NEPA. During the Scoping Process, per the standard consistent with the alternatives evaluated under previous Superfund or Resource Conservation and Recovery Act (RCRA) cleanup processes, NASA originally proposed to evaluate a range of cleanup standard levels, including the “Cleanup to Background” alternative required by the AOC, the “No Action” alternative required by NEPA, and other alternatives that are, consistent with the potential future use of the land. The latter alternatives include soil cleanup requirements to suburban residential, to industrial, and to recreational cleanup standards. Based on comments from some members of the public, DTSC, Senator Boxer, and guidance from the White House's Council on Environmental Quality, the DEIS now considers only the strictest “Cleanup to Background” and the least effective “No Action” alternatives. All other cleanup alternatives, consistent with both the Scoping Process and the potential future use of the land, were specifically removed from the DEIS.

The DEIS will consider a range of alternative technologies that meet NASA's objectives to clean up soil and groundwater contamination at the portion of the SSFL site administered by NASA. Implementation of this Proposed Action would occur by implementing one Demolition Alternative and one or more Cleanup Technologies, from the following: (1) Soil Cleanup Technologies: Excavation and Offsite Disposal, Soil Washing, Soil Vapor Extraction, Ex Situ Treatment Using Land Farming, Ex Situ Treatment Using oxidation, In Situ Chemical Oxidation, In Situ Anaerobic or Aerobic Biological Treatment; (2) Groundwater Treatment Technologies: Pump and Treat, Vacuum Extraction, Heat Driven Extraction, In situ Chemical Oxidation, In situ Enhanced Bioremediation, and Monitored Natural Attenuation.

NEPA requires analysis of the “No Action” alternative which in this case means no environmental cleanup at the site and/or no demolition of test stands and ancillary structures on the NASA-administered property.

GSA will conduct a separate environmental review under NEPA for the action of transferring the land out of NASA stewardship. The options could include reuse or redevelopment of the property under local, state, or private ownership.

DTSC is preparing a separate Environmental Impact Report (EIR) under the California Environmental Quality Act, which requires that State agencies give major consideration, when regulating public and private activities, to preventing environmental degradation and to identifying environmentally superior mitigations and alternatives, when possible. This State-led environmental review must identify the potentially significant environmental effects of a project and environmentally preferable alternatives to implementing the project. The EIR also indicates the manner in which significant effects could be mitigated or avoided. DTSC will analyze the potential environmental effects of environmental cleanup activities occurring SSFL-wide by NASA, Boeing, and DOE. NASA and DTSC have coordinated during these processes to maintain consistency pertaining to the analysis of the NASA-administered demolition and remedial activities. Cumulative effects of the proposed Boeing, DOE, and NASA demolition and remedial activities at SSFL will be considered. The DTSC EIR is likely to be prepared following publication of NASA's EIS, and could incorporate some of NASA's EIS analysis. A programmatic EIR will be developed that evaluates the remedial activities that will be conducted at SSFL by NASA, Boeing, and DOE, as well as project-specific EIRs that evaluate the localized remedial activities.

Public Meetings

NASA plans to hold two public meetings to receive comments on the DEIS regarding alternatives and environmental issues to be considered in the DEIS. The public meetings are scheduled as follows:

1. Corporate Pointe, West Hills, CA, Tuesday, August 27, 2013 from 2:00-4:00 p.m. at the Auditorium, 8413 Fallbrook Avenue, West Hills, CA 91304

2. Corporate Pointe, West Hills, CA, Wednesday, August 28, 2013 from 6:00-8:00 p.m. at the Auditorium, 8413 Fallbrook Avenue, West Hills, CA 91304.

NASA will consider all comments received in developing its Final EIS; comments received and responses to comments will be included in the Final document. In conclusion, written public input on environmental issues and Start Printed Page 47009concerns associated with NASA's cleanup of SSFL are hereby requested.
