San Joaquin County Green
in Practice - Be Green San Joaquin!
|
|
|
|
San Joaquin County as a whole is making changes in every Division
and Department to follow through on our commitment to sustainability, conserving
resources and "being green." As the leader for the County when it comes to
recycling, reducing and diverting waste, San Joaquin County Solid Waste has
encouraged new ideas at every level of the Solid Waste organization. We have
managed several pilot programs and empowered individuals at the operations level to try new
ideas to meet the goals
of saving money, conserving resources and lowering our environmental impact at County Facilities.
Below are some examples illustrating how Solid Waste and other San Joaquin County
Departments and Divisions are making an impact and going green. |
San Joaquin County Landfill Gas to Energy Program |
 After
a public bidding process San Joaquin County Public Works Solid Waste Division
and Ameresco Inc. have entered into
negotiations to construct a landfill gas (LFG) to energy facility at the
Foothill Sanitary Landfill. Based on
the amount of methane available at this site to generate electricity, two
generators with a combined capacity of 4.3 MW are being proposed. In this
public-private partnership, San Joaquin County will share in the revenues
created through the sale of the electricity produced. Prior to this
project, the methane produced at this site was being burned off through the use
of a flare. Methane has been targeted as a greenhouse gas that has more of
an impact on the environment than carbon dioxide.

Asphalt Road Patch Pilot |
|
Valley Asphalt's business model involved collecting asphalt shingles from businesses and the public and grinding this material up to make road base and asphalt patch. The County tested this material at several locations with different road repair needs. For some repairs, the product worked perfectly, for others the blend needed to be slightly modified for optimal results. Unfortunately Valley Asphalt closed its doors due to unforeseen circumstances. San Joaquin County is still exploring new ideas to reuse and recycle asphalt shingle material.

Tire Scraper Project - Reuse at Lovelace MRF Saves $$ |
|
Some of the heavy equipment used to move material
on the tipping floor at County facilities requires protective pads to act as a buffer
between the floor and the equipment, extending the life of each.
These expensive metal pads need to be replaced approximately every six weeks,
costing the County over $3,000 for each occurrence. The prototype pads worked well and are being used at the facility today. While there are some costs associated with making these pads on site, San Joaquin County is experiencing a cost savings of over $30,000 per year and is diverting waste by utilizing this program.

San Joaquin County Green Committee |
 San Joaquin County Green is a program that was
developed under the direction of the San Joaquin County Board of Supervisors. San Joaquin County's
Purchasing and Support Services was named the lead for this important
program.
As part of the County Green Program/Policy, a County Environmental Preferable Purchasing Committee or the "Green Committee" was created, comprised of representatives of multiple County departments, area chambers of commerce, local colleges and community based organizations. This Committee helps to communicate policy requirements and established
procedures, identify environmentally preferable products and services, and
provide information for employee awareness on environmentally preferable
procurement. The program reports to the Board of Supervisors annually on the
status of policy implementation and the environmental purchasing accomplishments
of departments and agencies. |

San
Joaquin Count Solid Waste Facilities
In a partnership between San Joaquin
County Solid Waste Division, the Road Maintenance Division and Valley Asphalt, a
local business, a pilot program was initiated to see if ground up asphalt
shingles, left over from roofing projects, could be used by the County as a
viable asphalt road patch material.
State regulations
require that erosion control measures be in place on landfill caps and slopes.
The most economical way to prevent erosion is through the use of vegetation at
landfill sites. The roots from this vegetation hold the soil together and
prevent erosion. The issue with vegetation is that watering the plants is
not an option, so the plants used must be very hardy and suited to San Joaquin
County's unique climate. At San Joaquin County's North County Sanitary
Landfill, a pilot project was launched to test the effectiveness of mulch and
compost on plant viability and vitality in a landfill setting. Partnering
with the UCCE based 
Employees at San Joaquin County facilities are encouraged to
find innovative ways to cut costs and divert materials from reaching the
landfill. The following example illustrates Solid Waste's strong
commitment to this practice:
San Joaquin County has adopted a Green
Purchasing Policy. This policy was adopted in order to:
