1.6.3 Employee Training Records

Prepare and maintain Employee Training Records throughout the term of the contract meeting applicable 40 CFR requirements. Provide Employee

Training Records in the Environmental Records Binder.

Train personnel to meet state requirements. Conduct environmental protection/pollution control meetings for personnel prior to commencing construction activities. Conduct additional meetings for new personnel and when site conditions change. Include in the training and meeting agenda: methods of detecting and avoiding pollution; familiarization with statutory and contractual pollution standards; installation and care of devices, vegetative covers, and instruments required for monitoring purposes to ensure adequate and continuous environmental protection/pollution control; anticipated hazardous or toxic chemicals or wastes, and other regulated contaminants; recognition and protection of archaeological sites, artifacts, waters of the United States, and endangered species and their habitat that are known to be in the area.

1.6.4 Non-Compliance Notifications

The Contracting Officer or delegated representative will notify the

Contractor in writing of any observed noncompliance with federal, state or local environmental laws or regulations, permits, and other elements of the Contractor's EPP. After receipt of such notice, inform the

Contracting Officer or delegated representative of the proposed corrective action and take such action when approved by the Contracting Officer or delegated representative. The Contracting Officer may issue an order stopping all or part of the work until satisfactory corrective action has been taken. No time extensions will be granted or equitable adjustments allowed for any such suspensions. This is in addition to any other actions the Contracting Officer or delegated representative may take under the contract, or in accordance with the Federal Acquisition Regulation or

Federal Law.

1.6.4.1 Mis-Dumping of Dredge Material Notification Procedure

Contractor shall immediately notify the Government COR, Government

Representative, and the Government Environmental Representative in the event of a draft loss occurs of 2 feet or greater. In the event that a draft loss has occurred scow shall be removed from rotation and inspected.

Inspection report shall be provided to the Government. If required by resource agencies, testing of contaminants shall be performed at no cost to the Government."

(a) E-Mail Alerts: The third-party system must also generate and distribute "e-mail alerts" regarding any degree of apparent dumping outside the project placement site ("mis-dumping"), and regarding any apparent substantial leakage/spillage or other loss of material en route to the project placement site.? Substantial leakage/spillage or other loss shall be defined as an apparent loss of draft of one foot or more between the time that the disposal vessel begins the trip to the project placement site and the time of actual disposal.? E-mail alerts for any disposal trip must be sent within 24 hours of the end of that trip to project placement site.

(b) 24-Hour Notification Requirement for Potential Leaks or Mis-Dumps: The permittee shall report any anticipated, potential, or actual variances from compliance with these project placement sites, and any additional project-specific Special Conditions, to the Government COR within 24 hours of discovering such a situation.? In addition, the permittee shall prepare and submit a detailed report of any such compliance problems on a weekly basis by noon Monday, to the to the Government COR.? These reports shall describe the cause(s) of the problems, any steps taken to rectify the problems, and whether the problems occurred on subsequent disposal trips.

1.7 ENVIRONMENTAL PROTECTION PLAN

The purpose of the EPP is to present an overview of known or potential environmental issues that must be considered and addressed during dredging. Include in the EPP measures for protecting natural and cultural resources, required reports, and other measures to meet the turbidity limits and other requirements in the MOU with the Central Valley Regional

Water Quality Control Board (CVRWQCB). Contingency plans should be discussed in the EPP that explain what actions will be taken if minimum freeboard isn't being maintained, if turbidity requirements are not being met, or if an adverse incident occurs. See 1.6.2 for requirements for pre-meeting with the Government prior to preparing the EPP for initial submission. Submit the EPP within 15 days after Contract award and not less than 10 days before the preconstruction meeting. Revise the EPP throughout the project to include any reporting requirements, changes in site conditions, or contract modifications that change the project scope of work in a way that could have an environmental impact. No requirement in this section will relieve the Contractor of any applicable federal, state, and local environmental protection laws and regulations. During dredging, identify, implement, and submit for approval any additional requirements to be included in the EPP. Maintain the current version onsite.

The EPP includes, but is not limited to, the following elements:

USACE Environmental Team.

In accordance with 40 CFR § 51.853(c)(2)(ix), the USACE has determined that the proposed agency action is exempt from the requirement to prepare a conformity determination with the State Implementation Plan under the

Clean Air Act because the project consists of maintenance dredging, no new depths are required, and disposal would be at approved disposal sites.

The Contractor shall be responsible for compliance with all Bay Area Air

Quality Management District (BAAQMD) regulations and standards including obtaining a permit if necessary, for operation of a stationary source of air pollutants. Mechanical failures resulting in violations of particulate matter or sulfur compounds (Regulation #2) would be handled through application for a variance from the BAAQMD.

Unless "optimized" or diesel powered equipment with the "Best Available

Control Technology" (BACT) emission devices are used, injection timing on diesel powered dredges and equipment shall be retarded two degrees from manufacturer's recommended setting to reduce air pollutant emissions.

Reformulated diesel fuel shall be used for all diesel powered dredges and equipment to reduce air pollutant emissions. Reformulated diesel fuel shall be a low sulfur, reduced aromatics diesel fuel meeting the following specifications, unless otherwise approved by the Contracting Officer or delegated representative: (1) Sulfur content less than 0.05 percent by

Plan for the Stockton Deep Water Ship Channel and Sacramento Deep Water

Ship Channel Maintenance Dredging and Dredged Material Placement Projects prepared by Mari-Gold Environmental Consulting Inc. for the U.S. Army Corps of Engineers, March 2011, Sacramento, California. The Contractor will submit a draft work plan to the Corps for review and comment, including a description of attaining 30% monitoring goal or higher if operating in an extension period, and a final work plan for Corps approval prior to initiating fish entrainment monitoring activities.

The work plan must also cover how pre-ground disturbance DMPS surveys will be conducted. The main goal of these surveys is to prevent adverse effects to terrestrial species in accordance with the BO's. The work plan should specify how the contractor will transit to each DMPS in advance of ground disturbance, as some DMPS are only accessible via boat or ferry.

The work plan must also identify how the Contractor will appropriately clean all previously used monitoring equipment prior to bringing it onto the project site. The Contractor must ensure that the equipment is free from soil residuals, egg deposits from plant pests, noxious weeds, and plant seeds. Consult with the USDA jurisdictional office for additional cleaning requirements. The Contractor's plan shall identify the fish entrainment monitoring biologist(s) who will be conducting the monitoring.

The fish entrainment monitor(s) monitoring the screen shall be trained and permitted to handle applicable ESA and CESA listed fish. Copies of the permits must be appended to the workplan prior to acceptance. The biologist(s) shall be experienced with Delta fish identification, use careful and limited handling, and take efforts to return all encountered fish back to sampled waters unharmed.

In addition, the work plan must identify how the Contractor shall maintain
