INTRODUCTION The Comprehensive Environmental Response, Compensation and Liability Act, (CERCLA), commonly referred to as "Superfund", was enacted in December 1980. Under CERCLA, the federal government is authorized to compel responsible parties to conduct cleanup of hazardous waste sites or initiate cleanup actions and then determine who is liable for the cost of clean-up. The Superfund Amendments and Reauthorization Act of 1986 (SARA) provided additional funds for Superfund cleanups but did not significantly change the basic principles of Superfund. Section 121 of CERCLA establishes general rules for selecting and implementing remedial actions at Superfund sites. This section specifies that remedial actions must comply with all applicable, relevant and appropriate requirements (ARARs). Standards, requirements, criteria or limitations under any federal environmental law are to be met if legally applicable or relevant and appropriate. Section 7(a) of the Endangered Species Act (1973) requires federal agencies to ensure that actions they authorize, fund, or carry out are not likely to jeopardize the continued existence of federally endangered and/or threatened species, or adversely modify or destroy the critical habitats of such species. In compliance with this Act, the U.S. Environmental Protection Agency (EPA) conducts informal consultations with the U.S. Fish and Wildlife Service (USFWS) to determine whether there are any federally endangered and/or threatened species or critical habitats present on or in the vicinity of CERCLA National Priorities List (NPL) sites. As a result of several recent informal consultations (Appendix A), the potential for the presence of the threatened plant species, swamp pink (Helonias bullata). has been identified within the vicinity of various NPL sites in New Jersey, including: 1. WiJson Farm, Ocean County . ; 2. Woodland Township/Route 532, Burlington County 3. Woodland Township/Route 72.,. Burlington County I CBA 008 01095 4. Chemsol Inc., Middlesex County 5. Evor Phillips Leasing, Middlesex County 6. Ewan Property, Burlington County 7. Ciba-Geigy, Ocean County 8. Lang Property, Burlington County Additionally, the potential for the occurrence of the habitat of another threatened plant, Knieskern's beaked-rush (Rhvnchospora knieskernii). has also been identified near several sites, including: 1. Ciba-Geigy, Ocean County 2. Lang Property, Burlington County 3. Woodland Township/Route 532, Burlington County 4. Woodland Township/Route 72, Burlington County The objective of this special study is to determine through a literature search and possible field survey, whether the federally threatened plant species swamp pink and Knieskern's beaked-rush or their habitats are present on the above-listed NPL sites. Furthermore, because the impact of remedial activities on the above-listed NPL sites may extend beyond the boundaries of the sites, study areas were defined based upon the location of potential habitat for the threatened plant species that may be affected by site remediation. The Scope of Work for this special study is comprised of task series covering the following items: 1. A review of existing information concerning the habitat requirements of the species; 2. A review of known sightings or locations of suitable species habitat in the vicinity of each of the NPL sites; 3. Development of a habitat survey work plan; 4. Implementation of the habitat survey work plan; and 5. Documentation of the presence or absence of the species in a technicaT report. -2- CBA 008 01096 j This Habitat Survey presents the findings of the literature review phase and field survey phase of the study.
