Forest Biomass Energy Initiatives
Forest Biomass Energy Initiatives Summary
Placer County includes over 550,000 acres of heavily forested landscapes in the central Sierra Nevada foothills and mountains. This area stretches from Auburn to Lake Tahoe, and includes portions of three national forests, numerous state parks, and 60% of Lake Tahoe’s west shore. The forested land is at significant risk for catastrophic wildfire due to the buildup of unnaturally dense vegetation following decades of successful fire suppression and exclusion. The County has experienced six major wildfires since 2001 burning more than 55,000 acres, including critically important upland watersheds and wildlife habitat.
The condition of Placer County's forests and how they are managed has a very strong effect on air quality. Wildfires are a significant source of air pollution, including fine particulate matter, ozone forming precursors, and air toxics, which are extremely detrimental to regional air quality and public health. Prescribed burning and open pile burning, important tools for reducing forest fuel loads, are also a significant source of air pollution.
To address the risk of catastrophic wildfire and improve air quality, the District has teamed with other public and private stakeholders to implement environmentally, economically, and socially sustainable forest management activities to restore these forested landscapes to a fire-resilient condition. The District's program activities, which you can learn more about in a presentation, brochure, and video (you may need to install an application called "Mediasite" to view this video), include:
- Forest Biomass Waste Utilization for Energy -- Emissions and Economic Analysis
- Biomass Waste for Energy Greenhouse Gas Offset Credit Protocol
- Forest Hazardous Fuels Reduction Treatments
- Distributed Biomass Energy Generation
- Prescribed Burning and Smoke Management
District projects have a wide range of social, environmental, and economic benefits including:
- improving air quality by reducing open pile burning and mitigating wildfire size and severity;
- generating renewable energy from excess forest wastes that reduces our reliance on fossil fuels;
- helping mitigate climate change by reducing greenhouse gases;
- helping reduce wildfires and wildfire effects to protect and improve watershed health (water quality and quantity), forest health, wildlife habitat, a sustaining supply of wood products, and forest recreation resources, and lower wildfire fighting costs;
- helping protect or increase local employment and rural community economic viability
Forest Biomass Waste Utilization for Energy -- Emissions and Economic Analysis
The District is sponsoring projects to cost effectively collect, process, transport, and utilize woody forest biomass wastes for renewable energy as an alternative to disposal by open pile burning or mastication (shred and scatter).
- In a public-private partnership demonstration project (report / Video with the United States Forest Service, Sierra Nevada Conservancy, and Sierra Pacific Industries, over 6,000 tons of forest slash from fuel hazard reduction treatments in the Tahoe National Forest were utilized for energy.
- Published peer reviewed technical article in the Journal of the Air and Waste Management Association documenting the air quality benefits of biomass energy as an alternative to open pile burning.
- Investing in a biomass waste for energy project at the Blodgett Forest Research Station in cooperation with the University of California Berkeley, College of Natural Resources, Center for Forestry.
The District was honored with a 2011 U.S. EPA Clean Air Excellence Award from the significant reductions in air pollutant emissions achieved through numerous forest waste energy projects.
Biomass Waste for Energy Greenhouse Gas Offset Protocol
The District has developed a protocol (protocol / summary) that provides a rigorous accounting framework for quantifying greenhouse gas emission offset credits for biomass waste for energy projects. The protocol has been peer reviewed and endorsed by numerous agencies (support letters). The protocol supports the use of biomass wastes for energy through the innovative monetary valuation of the greenhouse gas benefits. Greenhouse gas offset credits will be issued for compliance with California Environmental Quality Act mitigation obligations through a greenhouse gas exchange registry coordinated by the California Air Pollution Control Officers Association.
Forest Hazardous Fuels Reduction Treatments
The District is supporting on-going research work that is quantifying the air emissions reduction benefits that are provided by hazardous forest fuel reduction treatments (draft report). Fuels treatments involve the selective thinning and removal of trees and brush to return forest ecosystems to more natural fuel stocking levels resulting in more fire-resilient and healthy forests. Fuels treatments reduce air pollution by mitigating wildfire behavior, size and intensity, stimulating forest growth and vigor, and reducing tree mortality. Forest thinning also produces wood products that continue the sequestration of carbon. When fuels treatment projects include removal of excess biomass in the forms of limbs, tops, smaller trees and brush, the resulting biomass can be utilized for energy production and thus reduce the need for fossil fuels.
Distributed Biomass Energy Generation
The District is supporting the assessment of the air pollutant emissions benefits and economics of energy conversion technology suitable for small-scale distributed systems in Placer County, utilizing woody biomass wastes from forest fuel thinning treatments, timber harvest residues, and defensible space clearings.
We are also an advocate for a regulatory structure that recognizes the full environmental benefits of the use of forest biomass wastes for energy:
- Participated in the creation of the new Feed in Tariff program at the California Public Utilities Commission (CPUC).
- Assisted with the development of California Senate Bill 1122 which requires the CPUC to direct the three large Investor Owned Utilities in California to purchase a total of 50 MW of distributed forest biomass generation from facilities that produce less than 3 MW at strategic locations near forested areas at risk for catastrophic wildfire. We are assisting the CPUC by participating in the SB 1122 process:
Developing a fair power purchase agreement template
Making sure that the Investor Owned Utilities implement fair and equitable interconnection requirements.
Defining the term “strategic location” in content of communities at risk to catastrophic wildfire.
Prescribed Burning and Smoke Management
Prescribed burning is a vital ecological tool for forest management. We strongly support the use of prescribed burning in the appropriate situation and work with land managers to avert smoke impacts on the public. The District Smoke Management Program was adopted by the Board in December of 2001 in order to allow for the continuation of agricultural and prescribed burning as a resource management tool and provide increased opportunities for agricultural and prescribed burning while at the same time minimizing smoke impacts to the public. This program is intended to help minimize smoke impacts on air quality and the public through planning, use of automated weather stations to provide meteorological data to predict smoke transport and dispersion, and the use of fuel load reduction prior to burning.
