Cleanup Areas for Background

This page highlights the NASA-administered portions of SSFL in an orange outline. These portions are a backwards letter L in the middle and a smaller square shape in the upper right corner.  Areas of purple color identify areas that would require remediation under the background cleanup standard (Proposed Action).  These areas are located within each of the NASA-administered portions of SSFL, mostly in the southern and northern parts.

Historic Properties on Area II

The graphic shows the backwards L shaped portion of the NASA-administered Area II at SSFL and is highlighted with a red outline.  Within that area are three individual smaller areas highlighted in light green to show that they are historic districts.  These areas, listed from north to south, are the Alfa Test Area Historic District, the Bravo Test Area Historic District, and the Coca Test Area Historic District.

Two Historic/Structural surveys were performed in 2007 and 2009:

  • 3 historic districts identified
    • 9 structures found individually eligible for the National Register of Historic Places (NRHP)
    • 27 structures considered 'contributing' to the historic districts

Conceptual Thinking on Building Demolition Selection

  • Is contamination around structure?
    • Yes: In coordination with DTSC, can cleanup goals be met without demo?
      • Yes: Historic?
        • Yes: Decide demo or not based on consultation with SHPO, ACHP, and public, and coordination with GSA
        • No: Building could be demolished If no demolition, conduct cleanup and maintain structure
      • No: Is structure historic?
        • Yes: In coordination with SHPO, ACHP, and public, determine if structure should be saved
          • Yes: Can contamination be safely left in place?
            • Yes: Implement any measures to protect public health and maintain structure
            • No: Conduct demo and cleanup
          • No: Conduct demo and cleanup
        • No: Conduct demo and cleanup
  • No: Is structure historic?
    • Yes: Decide demo or not based on consulta-tion with SHPO, ACHP, and public, and coordination with GSA
    • No: Building could be demolished If no demolition, maintain structure

What is the Action

This page highlights the NASA-administered portions of SSFL in an orange outline. These portions are a backwards letter L in the middle and a smaller square shape in the upper right corner.  There are purple zones that identify areas that would require remediation under the background cleanup standard (Proposed Action in the draft Environmental Impact Statement).  These zones are located within each of the NASA-administered portions of SSFL, mostly in the southern and northern parts.

Identify Resources

This figure presents biological resources identified within the NASA-administered portions of SSFL and the relationship to the background cleanup standard.  The NASA-administered portions of SSFL are highlighted in an orange outline.  The purple zones identify areas that would require remediation under the background cleanup standard (Proposed Action in the draft Environmental Impact Statement).  The figure shows results of field mapping of flora and fauna surveys at SSFL, including the ringtailed cat, loggerhead shrike, coast horned lizard, least bell’s vireo, two-striped garter snake, plummer’s mariposa lily, slender mariposa lily, Santa Susana tar plant, black walnut tree, southern willow scrub, venturan coastal sage scrub, coat live oak, sandstone, rock basin, and wetlands.  There are a few areas where the soil cleanup would impact biological resources.

Evaluate Potential Impacts

Activities Assessed
Air Quality Increase in criteria pollutant emissions from both onsite and offsite activities including excavation or other ground disturbing activities, demolition, erosion, equipment exhaust, exhaust from crew commutes, and exhaust from heavy trucks used to haul materials and soils to the appropriate licensed waste disposal facilities.
Water Resources Effects on surface water and groundwater quality, hydrology, and infiltration from the various cleanup approaches, changes in surficial flow patterns as a result of broad excavation or removal of structures or paved surfaces.
Traffic Effects on roadway operations, road conditions, parking, and emergency access from heavy truck use within and accessing SSFL.

NASA Impact Definitions

Impact Description
No Impact No impacts would be expected.
Negligible Impacts would not be expected to be measurable, or would be measurable but too small to cause any change in the environment.
Minor Impacts would be measurable but within the capacity of the affected system to absorb the change.
Moderate Impacts would be measurable but within the capacity of the affected system to absorb the change; or the impacts could be compensated for with mitigation and resources so the impact would not be substantial.
Significant Impacts would be measurable but not within the capacity of the affected system to absorb the change, and without major mitigation, could be severe and long lasting.
Quality Beneficial - would have a positive effect on the physical, social, or cultural environment.
Negative - would have an adverse effect on the physical, social, or cultural environment
Duration Short term – would occur only during the proposed demolition and immediate remediation period.
Long term – would continue beyond the proposed demolition and immediate remediation period.
Proximity Local – would occur within the NASA-administered property at SSFL.
Regional – would occur outside the NASA-administered property at SSFL.

Cumulative Impacts?

Cumulative impact is the impact on the environment which results from the incremental impact of the action when added to other past, present and reasonably foreseeable future actions regardless of what agency (federal or non-federal) or person undertakes the actions. Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time (40 CFR Section 1508.7).

  • Actions of a similar character, which could affect the same environmental resources as NASA proposed action such as Boeing and DOE cleanups and demolition

Mitigations

Mitigation inludes:

  • Avoiding the impact altogether by not taking a certain action or parts of an action.
  • Minimizing impacts by limiting the degree or magnitude of the action and its implementation.
  • Rectifying the impact by repairing, rehabilitating, or restoring the affected environment.
  • Reducing or eliminating the impact over time by preservation and maintenance operations during the life of the action.
  • Compensating for the impact by replacing or providing substitute resources or environments.
