Underground Storage Tanks

The purpose of this program is to protect public health and the environment from exposure to hazardous materials stored in underground storage tanks (USTs). The primary focus is on protection of groundwater from contamination. Activities include inspection, permitting, monitoring, repair, installation and removal of USTs. UST sites with identified contamination are referred to the Environmental Health Site Mitigation Unit for cleanup oversight.

Food Events

Please be advised that if your event will include food vendors, then you are required to submit a completed “Event Food Facility Organizer Permit Application” 14 days prior to event with a check made payable to Mono County Health Department or an online payment. Additional penalty fees will apply 13 days or later.

Cottage Food Operations

New State Law Effective January 1, 2013

Cottage food operations are allowed to produce certain non-potentially hazardous foods. These are foods that do not support the rapid growth of bacteria that would make people sick when held outside of refrigeration temperatures. The list of approved cottage food categories and their ethnic variations, which cottage food operations are allowed to produce, are listed below. The list will be maintained and updated by the California Department of Public Health (CDPH) on its Internet website as necessary.

Hazardous Waste

The purpose of this program is protection of public health and the environment from exposure to hazardous wastes by regulation of the businesses and industries that generate hazardous waste. This is accomplished through a comprehensive program of inspection, chemical emergency response, surveillance, complaint investigation, and assistance to industry, enforcement and public education.

Aboveground Storage tanks

The purpose of this program is to protect waters of the state (surface water and groundwater) from exposure to (petroleum-based) oil stored in aboveground storage tanks by confirming compliance, for specified facilities, with the federal Spill Prevention, Control, and Countermeasure rule. This is achieved through routine, periodic, and complaint inspections, surveillance, enforcement, public education, and assistance to industry.

Vector Control

The Vector-Borne Disease Section (VBDS) protects the health and well-being of Californians from diseases transmitted to people from insects and other animals.

Small Water System Program

The goal of the small water system program is to ensure that each small public water system provides the users with wholesome potable water which meets State standards and regulations. This program provides regulatory over site to ensure all small public water system operators are issued a water system permit to serve water to the public.  This procedure outlines the general guidelines to follow when issuing a small water system permit to a new small water system.
