Roberts Ditch RMA (Streambed Alteration Agreement EPIMS Notification No. COL-57415-R2)

The California Department of Fish and Wildlife has issued a Streambed Alteration Agreement under EPIMS Notification Number COL-57415-R2 to the Roberts Ditch Irrigation Company, authorizing annual maintenance dredging of Roberts Ditch in Colusa County, California, to ensure reliable water diversion for irrigation purposes during the growing season. The work involves removing up to 3,000 cubic yards of silt and sediment annually using a long-reach excavator accessed via existing entry points on the east side of the channel, with the goal of maintaining a minimum three-foot depth and an average width of fifteen feet. This activity falls under categorical exemptions under the California Environmental Quality Act (CEQA) Sections 15301 and 15304, which classify the project as routine maintenance of an existing facility and a minor alteration to land with negligible environmental impact. The project is not subject to federal acquisition regulations or procurement requirements, as it is a state-level environmental compliance agreement governed by the Fish and Game Code Section 1602, and no contractual pricing, line items, or funding identifiers are specified. The contractor is responsible for performing the dredging in accordance with specified environmental protections, including the prohibition of removing healthy, mature, or scenic trees and limiting spoil disposal to authorized areas approved by state and federal agencies. Oversight and approval authority rests with the California Department of Fish and Wildlife, with Claire Bryant, Environmental Scientist, and Tanya Sheya, Environmental Program Manager, serving as the primary points of contact for regulatory compliance. The agreement does not include formal contract terms such as payment details, invoicing methods, accounting codes, or evaluation factors, as it is not a competitively awarded procurement but rather an administrative authorization for a regulated activity. The Roberts Ditch Irrigation Company, represented by Vincent Andreotti, is expected to carry out the work on an annual basis without a defined contract duration, and no UEI, CAGE codes, or socioeconomic certifications are required or provided. The project is localized to River Mile 144.2 along the Sacramento River and does not involve new infrastructure, expansion, or federal procurement structures.
