SUPPLEMENTARY INFORMATION:

Public Involvement

NASA solicited public and agency review and comment on the environmental impacts of the Proposed Action through:

1. Publishing notices of availability of the Draft EA in local newspapers and the Federal Register ;

2. Making the Draft EA available for review at local public libraries;

3. Publishing the Draft EA on the NASA Web site; and

4. Consulting with Federal, state, and local agencies.

Comments received were considered in the final EA. Comments and responses to comments are provided in Appendix G of the final EA.

Proposed Action

NASA proposes to carry out a variety of missions involving the launch of routine payloads over the next several decades.

By collecting a range of unique scientific and engineering data from space and transmitting the data to Earth, NRP spacecraft would support NASA's strategic goals:

(a) To extend and sustain human activities across the solar system;

(b) To expand scientific understanding of the Earth and the universe in which we live; and

(c) To create the innovative new space technologies for our exploration, science, and economic future.

The proposed action includes preparing, launching and decommissioning missions identified as routine payload missions. Routine payload spacecraft would be placed into Earth orbit or into Earth-escape trajectories (i.e., solar orbit) using one of a group of expendable launch vehicles (ELVs) routinely launched from Cape Canaveral Air Force Station (CCAFS), Florida; Vandenberg Air Force Base (VAFB), California; Reagan Test Site at the U. S. Army Kwajalein Atoll in the Republic of the Marshall Islands (USAKA/RTS); NASA Wallops Flight Facility (WFF), Virginia; and, Kodiak Launch Complex (KLC), Alaska. The launch vehicles include: Athena I and II, the Atlas V family, the Delta family, the Taurus family, the Falcon family, the Pegasus XL, and the Minotaur family.

Alternatives

Alternatives to the proposed action that were evaluated include: (1) Utilizing a foreign launch vehicle or, (2) NASA would not launch spacecraft missions defined as routine payloads (the “no action” alternative). U.S. launch vehicles are proposed for launch of NASA routine payloads. The nature of environmental impacts, payload processing, launch sites, and other related information for foreign launch systems are generally not as well known or as well documented as for launches from the U.S. In addition, use of non-U.S. launch vehicles requires individual consideration, review, and additional documentation. Therefore, foreign launch vehicles were not considered to be reasonable alternatives for the purpose of this routine payload spacecraft EA. The no action alternative would not meet the purpose and need for the action.

Environmental Impacts

Maximum potential impacts to the human environment associated with the proposed action arise from the normal launch of the Atlas V (largest solids from CCAFS), the Delta IV (largest solids from VAFB), and the Delta II 2925 (largest hypergolic propellant load from CCAFS and VAFB). Launch accident scenarios have also been addressed and indicate no potential for substantial environmental impact to the human environment. Air emissions from the exhaust produced by the solid propellant and first stage primarily include carbon monoxide, hydrochloric acid, aluminum oxide in soluble and insoluble forms, carbon dioxide, and deluge water mixed with propellant by-products. The primary emission products from the liquid engines include carbon dioxide, carbon monoxide, water vapor, oxides of nitrogen, and carbon particulates. Air impacts will be short-term and not substantial. Short-term water quality and noise impacts, as well as short-term effects on wetlands, plants, and animals, would occur in the vicinity of the launch complex. These short-term impacts are of a nature to be self-correcting, and none of these effects would be substantial. There would be no impact on threatened or endangered species or critical habitat, cultural resources, or floodplains.

NASA routine payloads would follow the NASA guidelines regarding orbital debris and minimizing the risk of human casualty for uncontrolled reentry into the Earth's atmosphere. None of the NASA routine payload missions covered under the EA would have radioactive materials aboard the spacecraft, except for the possibility of very small quantities on certain missions for instrumentation purposes. Consequently, no potential substantial adverse impacts from radioactive substances are anticipated. No other individual or cumulative impacts of environmental concern have been identified.

The level and scope of environmental impacts associated with the launch of NASA routine payload are well within the envelope of impacts that have been addressed in previous EAs/FONSIs concerning other launch vehicles and spacecraft. NASA routine payloads would not increase launch rates nor utilize launch systems beyond the scope of approved programs at the identified launch sites. No specific NASA routine payload processing or launch activities have been identified that would require new permits and/or mitigation measures beyond those currently in place or in coordination. No significant new circumstances or information relevant to environmental concerns associated with the launch vehicles have been identified which would affect the earlier findings. NASA is formally adopting the existing launch vehicle/launch site NEPA documentation referenced in Appendix A of the final EA.

As specific spacecraft missions are sufficiently defined, they will be reviewed to determine whether or not the proposed mission falls within the scope of the final EA. If a proposed mission is found to be inconsistent with the routine payload categorization, additional environmental review will be conducted and documented, as appropriate.

NASA has reviewed the final EA prepared for the launch of Routine Payloads on expendable launch vehicles and has concluded that the final EA represents an accurate and adequate analysis of the scope and level of associated environmental impacts. NASA hereby incorporates the final EA by reference in this FONSI. On the basis of the final EA, NASA has determined that the environmental impacts associated with the proposed action would not individually or cumulatively have an impact on the quality of the human environment. Therefore, an ( printed page 72220) environmental impact statement is not required.
