Whenever you “throw something away” it’s taken to the Monterey Peninsula Landfill – the final disposal site for approximately 600,000 tons of municipal solid waste delivered to the facility each year.

This 461-acre site began operating as a sanitary in 1965 and is located in Unicorporated Monterey County north of City of Marina (circa 1975) and south of the Castroville area. Engineers estimate that it has space for more than 100 years of waste. Currently, portions of the Landfill have been filled to an elevation of 130 feet , about half the height of the final landfill.

The entire Monterey Peninsula Landfill has been engineered with controls in place to separate waste safely from the environment. The landfill is composed of modules or cells that are developed one at a time. The 14-acre module most recently developed was completed in June 2021.The construction of a new module begins with an engineered single composite liner made from a 2 foot thick layer of clay, covered with a heavy plastic liner. Leachate collection pipes and sand are placed above the liner to catch any liquids draining from the waste – these are recirculated through the landfill. Finally, a 2 foot thick layer of sand or compost is placed over the sand drainage layer to protect the drainage system and plastic liner from being damaged by heavy machinery and waste materials.

Cover your load! Uncovered loads may be charged double. Uncovered trucks are one of the primary sources of litter found along our roadways. To report a litter violation from a motor vehicle, visit

All Loads Subject to Hazardous Waste Load Checking

Hazardous and other prohibited materials, as defined under California law and regulations, may not be disposed at the Monterey Peninsula Landfill or the Materials Recovery Facility (MRF). If hazardous materials are found in loads, the hauler is responsible for all costs associated with management of the hazardous material. In addition, ReGen Monterey may notify state and local regulatory agencies, and the responsible party or parties may be subject to civil or criminal prosecution, or both.

Note: Classification of all materials is subject to scale house personnel’s discretion at time of acceptance.


ReGen Monterey offers the following facilities to make it convenient for you to reduce, recycle and properly dispose of your household hazardous materials before refuse is deposited in the landfill:

On August 31, 2021, Governor Newsom signed Assembly Bill 332 and the bill takes effect immediately. AB332 adopts new Alternative Management Standards (AMS) for treated wood waste (TWW) that are codified in Health and Safety Code section 25230. As a result of the chaptering of the bill, all treated wood waste variances issued by DTSC since March 2021 are now inoperative and have no further effect. The variances are no longer necessary because they have been replaced by the AMS. The new AMS are similar to the rules that applied under the variance program, except that no variance is required.

The DTSC requires customer information is collected when TWW is brought in for disposal.

Treated Wood Waste customer information forms must be completed before arriving to the ReGen Monterey.

Medications should never be flushed down the drain.

For proper disposal of pharmaceuticals, the best solution is to return them to a pharmacy with a take-back program. Please check with your local pharmacy to see if they offer a take-back program. The Household Hazardous Waste program can receive “over the counter” medication and medical sharps (safely sealed in a sharps container and/or sealed and labeled plastic bottle).

For a listing of free safe collection sites for unused medications in Monterey County, visit Don’t Rush to Flush.
