CERCLIS-NFRAP: CERCLIS No Further Remedial Action PlannedSource: EPATelephone: 703-413-0223As of February 1995, CERCLIS sites designated "No Further Remedial Action Planned" (NFRAP) have been removed

from CERCLIS. NFRAP sites may be sites where, following an initial investigation, no contamination was found,contamination was removed quickly without the need for the site to be placed on the NPL, or the contaminationwas not serious enough to require Federal Superfund action or NPL consideration. EPA has removed approximately25,000 NFRAP sites to lift the unintended barriers to the redevelopment of these properties and has archived themas historical records so EPA does not needlessly repeat the investigations in the future. This policy change ispart of the EPA’s Brownfields Redevelopment Program to help cities, states, private investors and affected citizensto promote economic redevelopment of unproductive urban sites.

Appendix Q South Delta Improvements Program


Prepared by the U.S. Department of the Interior, Bureau of Reclamation.

Introduction The California Department of Water Resources (DWR), in coordination with the U.S. Department of the Interior, Bureau of Reclamation (Reclamation), proposes to implement the South Delta Improvements Program (SDIP) to improve water quality, water conveyance, and fish conditions in the south Sacramento–San Joaquin River Delta (Delta). The SDIP attempts to balance the need to increase the current regulatory limit on the State Water Project (SWP) Harvey O. Banks Pumping Plant (SWP Banks) from 6,680 cubic feet per second (cfs) to 8,500 cfs with the need to improve local agricultural diversions and migratory conditions for Central Valley fall- and late fall–run Chinook salmon in the San Joaquin River. The SDIP project consists of the following new components located in the Delta:

modify operations to increase diversions into Clifton Court Forebay (CCF) and increase pumping at SWP Banks;

construct and operate three flow-control structures (gates) to improve existing water level and circulation patterns for south Delta water users on Middle River, Grant Line Canal, and Old River;

construct a fish control gate at the head of Old River to improve conditions for salmon migrating along the San Joaquin River;

dredge various channels within the south Delta to improve conveyance; and

extend up to 24 agricultural diversion intake facilities.

The SDIP, in addition to the new components listed above, includes an agreement between DWR and Reclamation to better coordinate operations of the Central Valley Project (CVP) and SWP. The agencies propose to convey up to 100,000 acre-feet per year (af/yr) of Level 2 CVP refuge water at SWP Banks, and use up to 75,000 af/yr of CVP water to reduce SWP in-basin obligations for San Francisco Bay/Sacramento–San Joaquin River Delta (Bay-Delta) water quality and flow requirements.

quantities (by half) are proposed prior to implementation of the full SDIP and 8,500 cfs SWP Banks permit increase.

Trinity River Division Operations The Trinity River Division of the CVP includes facilities to store and regulate water in the Trinity River, as well as facilities to divert water to the Sacramento River Basin. Trinity Dam stores and regulates the flow of the Trinity River. Trinity Reservoir is formed behind the dam and has a maximum storage capacity of approximately 2.4 million acre-feet (maf). Trinity Reservoir stores water for release to the Trinity River or for export to the Sacramento River Basin via Lewiston Reservoir, Carr Tunnel, Whiskeytown Reservoir, and Spring Creek Tunnel where it commingles in Keswick Reservoir with Sacramento River water.

Trinity River Division operations are primarily governed by (1) the need for exports to the Sacramento Basin to increase CVP water supply and/or hydropower production, (2) satisfying fish and wildlife flow and temperature requirements along the Trinity River, and (3) maintaining flood control in accordance with safety of dams criteria.

Transbasin Exports Exports of Trinity water to the Sacramento Basin provide increased water supply for the CVP and are a major source of CVP power generation. The determination of annual export volumes is made in coordination with the operation of other CVP water supply reservoirs. The seasonal timing of exports attempts to make the most effective use of Trinity Reservoir supplies to satisfy temperature objectives on both the Trinity and Sacramento Rivers.

Fish and Wildlife Requirements Based on the December 2000 Trinity River Main Stem Record of Decision, 368–815 thousand acre-feet (taf) is allocated annually for Trinity River flows. Temperature objectives for the Trinity River are set forth in State Water Resources Control Board Water Rights Order 90-5 and vary by reach and season. Objectives generally specify maximum daily average temperatures of 60ºF during the summer period and 56ºF during the fall.

Flood Control Although not an authorized purpose of the Trinity River Division, Trinity Dam provides flood control benefits through Reclamation’s safety of dams operations

to prevent overtopping. The safety of dams criteria attempt to prevent storage from exceeding 2.1 maf during November through March.

Summary of SDIP Modeling Technical modeling analyses have been developed for the draft SDIP EIR/EIS (October 2003) to evaluate potential impacts throughout the CVP/SWP system. CALSIM II model studies were prepared for “Base” and project “Alternatives”. Key assumptions pertaining to the Trinity River in these model studies are: (1) Trinity River Record of Decision (ROD) flows (369–815 taf per year), (2) Reclamation’s safety of dams storage levels, and (3) annual and season export operations consistent with reduced Trinity volume for transfer to the Sacramento Basin. CALSIM II simulates Trinity Reservoir operations as an integrated component of the CVP and balances storage with that in Shasta. The CALSIM II model simulates projected monthly CVP and SWP operations for a 73-year period that approximates the hydrologic conditions of water years 1922–1994. A brief summary of the draft SDIP modeling results is presented below. In the discussion and figures that follow, the “Alternative” denotes SDIP Alternative 2A because evaluation of this alternative illustrates the most impacts that could occur from implementation of any of the SDIP alternatives. It should also be noted that SDIP CALSIM II modeling studies are currently being updated to provide consistency with Reclamation’s Operations Criteria and Plan (OCAP) modeling packages.

Trinity River Flows The SDIP CALSIM II modeling indicates that there will be no significant change to Trinity River flows due to the SDIP. The minimum instream flow requirements are the same under the Base and Alternative conditions, such that the only flow changes that should occur will be during spill conditions. As can be seen in Figures Q-1 and Q-2, the annual volumes, frequency, and monthly patterns of flow in the Trinity River flow are nearly identical to those in the Base scenario.

Trinity Reservoir Storage The CALSIM II modeling indicates that Trinity Reservoir storage is not significantly changed during conditions in which the Base storage was above 1.0 maf (Figure Q-3). The number of years in which end-of-September Trinity Reservoir storage falls below 1.0 maf is 21 times in both the Base and Alternative scenarios. Similarly, end-of-September Trinity Reservoir storage falls below 600 taf in nine years in both scenarios. The lack of significant impacts at the lower storage levels is important because of the relatively warmer temperatures that occur under these conditions and in terms of effects on

reservoir recreation. During wetter conditions, greater releases are made from Shasta Dam to support CVP Delta exports and limited SWP Delta obligations, as part of the increased coordination between the CVP and SWP. Trinity River exports to the Sacramento Basin are subsequently increased to support Shasta storage. As is shown in Figure Q-3, these impacts on storage are limited to years in which end-of-September storage is greater than 1.0 maf.

Trinity River Exports As discussed above, exports of Trinity water to the Sacramento Basin are used to augment water supply for the CVP and operated to assist balancing amongst Trinity, Shasta, and Folsom reservoir storage. CALSIM II modeling indicates that greater imports occur during wetter years to support slightly greater releases from Shasta. Because these changes are occurring during higher Trinity Reservoir storage conditions, the impacts on Sacramento River and Clear Creek temperature will be limited. The overall level of imports is not significantly changed from the Base scenario (Figure Q-4). The average annual simulated Trinity River export is 586 taf in the Base study and 587 taf in the Alternative. The timing of Trinity exports is approximately the same as that simulated under the Base conditions. The model results show minor increases in August and October and nearly equivalent decreases in November through February (Figure Q-5).

Summary Technical modeling analyses using the CALSIM II model have been developed to approximate the impact of the SDIP on the interconnected CVP-SWP systems. The SDIP supports greater Delta exports by increasing the permitted pumping at SWP Banks to 8,500 cfs and through improvements to the South Delta barriers and channels. The modeling studies performed to date indicate that the impacts to the Trinity River flows and storage conditions are not likely to be significant. Simulated Trinity River flows approximate the Base condition. Trinity Reservoir storage is exercised more under higher storage conditions in the Alternative to support balancing with Shasta Reservoir, but is not significantly changed under lower storage conditions. The number of years in which Trinity Reservoir storage falls below 1.0 maf and 600 taf is the same under both the Base and the SDIP alternative scenarios.
