Call to Order Mark Weir called the meeting to order at 6:01 p.m. in the Siskiyou Room. Commissioners Bryan Sohl, Shel Silverberg, Jim McGinnis, Risa Buck, Jim Hartman and Councilor Rich Rosenthal were present. Staff member Adam Hanks was present. Commissioners Thomas Beam, Marni Koopman, and Roxanne Biegel-Coryell were absent. 2. Consent Agenda Buck/Silverberg m/s to approve the minutes of December 17, 2014. Voice vote: All ayes. Motion passes. 3. Announcements The next commission meeting will be held on February 25. The climate and energy subcommittee will meet on February 18th from 2-4 at the SOU library. Buck let the group know that SOU will be hosting the movie, Bag-It on February 10 from 5:30— 7:30. Both Buck and Weir will be participating in a panel discussion following the movie. Buck thanked the City for using mostly all-durable goods at last night's State of the City Celebration. The only things she noted as not being durable were napkins and nametags. She thought the event set a good tone for the rest of the community. 4. Public Forum Louise Shawkat—thanked the group for the amount of work they do, especially the climate and energy subcommittee. She would like the group to consider working with local banks to provide loans for conservation and energy retrofits/remodels. This would help owners who otherwise can't afford to do so improve their energy efficiency. Reminded the group that we need a plan to develop more alternate energy resources. Huelz - Stated he had also given this information at a recent City Council meeting. He informed the group that global warming is bad and more disasters are on the way. Society created this problem with bad growth. The least Ashland could do was stop building homes and buildings designed with carbon pollution. Stopping bad growth would not ruin the economy. Bad growth reduces quality of life. He also suggested that we lease Tesla vehicles for Council members, so they know what we can achieve. Believes that people in town do not want growth and that our water and streets are at their maximum capacity so he wonders why people are still coming here and ruining our quality of life,making life more dangerous, and adding more carbon. He would like to create a new department, since no building would mean no need for any planning or building departments. This new department would focus on programs for efficiency and he would run it. He would call it the Ashland Renewal Acquisition Department. He will send links to the Commission on a recent speech which talks about the carbon problem and gives clear solutions of how to solve it. 5. Reports/Presentations/Updates Minutes for the Conservation Commission January 28,2015 Page 2 of 4 Council—Councilor Rosenthal informed the group that he's been re-appointed as the liaison to this commission for the next year. On January 2nd, Council approved their goals for the next biennium and 22.1 (Develop and implement a community climate change and energy plan) was approved and labeled a priority goal for the Council. Next Tuesday(February 2) SOU is presenting information to the Council regarding their co-generation project, if any commissioner wants to learn more. Recently, Representative Buckley and Senator Bates presented to Council their upcoming legislative priorities. Climate change is one of their top priorities. McGinnis thanked Rosenthal for last night's State of the City Event and expressed his appreciation that it focused largely on vision rather than entirely on history. Buck agreed and hopes that the City continues to be more celebratory. City Conservation chi Operations—Hanks updated the group on installation of LED street lights. Ones for Siskiyou Blvd. have been ordered and they are receiving partial funding from BPA. McGinnis requested that information regarding savings from the LED lights be kept for future reporting (particularly as part of the Climate and Energy plan). Hanks informed the group that results of a recent energy audit mean changes to water heating system at the waste-water plant, which should provide good savings. Quarterly Report from Gary Sisk(Ashland School District)—Mr. Sisk informed the group that the report in the packet shows a snapshot of what they are currently working on. He feels it is very critical that large entities like the school district track and work hard to make their buildings as energy efficient as possible. Described to the group some of the LED lighting changes they are making. The true cost savings for LED lighting is not in the energy savings but in the maintenance savings. If they only have to replace lighting once every few years rather than once a year, it's a huge savings. Group thanked Mr. Sisk for his report, enthusiasm and continued efforts. Group discussed ways they can encourage the school district to continue becoming more efficient. Conservation Awards sub-committee—Next meeting of the subcommittee is Monday(February 2) at Recology at 4:00 p.m. So far both the middle school and John Muir school are on-board with the Earth Bowl idea. The committee is hoping for eight teams of four, mixed boys and girls. They are looking for three coaches to supervise the kids and are hoping to get the science teachers involved. Chip Lindsey from ScienceWorks would like to help edit the questions. The committee would like the commission to consider skipping the regular April meeting and instead have the "meeting"be attending and working on the Earth Bowl event. The group agreed to have further discussion of this request at the February meeting. Hartman/Silverberg m/s to spend up to $100 to bring lunch to the middle school science teachers to discuss their possible participation. No discussion. VoiceVote: all ayes. Motion passes. 6. Old Business Sneak Preview Column—Hartman/Buck m/s to approve the February column as submitted. Discussion: It would have been helpful if this topic was actually one month out for better Minutes for the Conservation Commission January 28,2015 Page 3 of 4 confirmation of dates and details. Group recognized that this wasn't possible due to submittal due dates. Group agreed that webpage for additional information would be ashland.or.us/EarthBowl. Voice Vote: all ayes. Motion passes. Group discussed possibility of having a column regarding Gary Sisk's work with the School District. Agreed that it would be a good idea. Upcoming column topics: • March—Energy Efficiency, written by Hanks • April—Water Conservation, written by Weir • May— Overview of Climate Action Plan, written by Koopman and McGinnis • June— Compost Classes, written by Buck • July— School Efficiency Improvements, written by Hartman Carbon Fee/Dividend Discussion—discussion postponed due to absences of group members. Earth Day—Buck informed the group that she expects a request to the commission at the February meeting to support the Earth Day event. She would like the group to take a few minutes to decide if they are interested in participating or sponsoring the event this year. Last year the commission supported with money but did not participate. With the upcoming Earth Bowl the group has transitioned away from the Earth Day event. Group discussed pros and cons of participating in the Earth Day event. Discussed whether it would be the right venue to get the message out. Group determined that it's probably not the best as there is too much going on for the message to really be heard. Group discussed how difficult it is to say yes or no to any financial requests as they don't really have a clear picture of priorities and budget regarding those priorities. Silverberg agreed to create a draft "budget" for the commission's financial priorities. Group is to send him projects/ideas as well as rough costs so he can begin prioritizing. Climate and Energy Sub-committee Presentation—McGinnis informed the group that the meetings have been going well. He gave an overview of the plan to-date. The biggest changes from the last version are inclusion of examples in the appendices. They would like the group to approve it and move forward with the proposed document. McGinnis/Buck m/s to adopt the plan, minus the Corvallis plan appendix, for sending to Council in their March meeting. Discussion: Group discussed what was left to be done (the presentation). Councilor Rosenthal believes this plan is what the Council requested. Group discussed the format of the groups in the plan and determined that using a Technical Advisory Group and a Policy Group format would work best. They agreed to amend the plan accordingly. Voice Vote: all ayes. Motion passes. 7. New Business Compost Classes—Buck informed the group the new teacher will be Jim Flarity. Planning for a total of four classes and hoping to utilize the compost areas at the Recycle Center in-class. Minutes for the Conservation Commission January 28,2015 Page 4 of 4 Buck/McGinnis m/s to approve the new teacher for four classes, running from 10:00 a.m.— noon and that two classes will be basic classes, with the remaining two advanced classes. Voice Vote: all ayes. Motion passes. Group discussed possibility of a rebate for those who have taken both the basic and advanced classes and show proof of purchase on start up system. Agreed this topic should be on a future agenda (maybe April or May). Group agreed they will have a later discussion on approving a gift certificate for the teacher as that money would come from the next budget cycle. Fourth of July—Buck requested that the group consider ideas for what to do in/at the parade and new ways to "get the message out". 8. Wrap Up Group requested the following be on the upcoming agenda: Climate Action Plan Follow-up Earth Bowl/Conservation Awards Earth Day Event Draft budget/financial priorities Carbon Fee/Dividend Fourth of July Meeting adjourned at 7:56 p.m. Respectfully submitted, Diana Shiplet Executive Secretary MENEM Informatleon Sheet Southern Oregon University is considering replacing the aging natural gas boiler system that heats campus buildings with a biomass cogeneration plant. The biomass facility would use forestry byproducts as a fuel source and produce both heat and electricity. Background SOU is currently heated by a natural gas fired boiler system. Two of the boilers are reaching the end of their useful life and need to be replaced to meet the increasing demand for campus heating. In 2011 and 2013, SOU commissioned three different studies to explore options for replacing the outdated boilers. These studies considered five alternatives, including two cogeneration options - one fueled by natural gas and the other by biomass. Cogeneration produces steam for heating campus buildings and generates electricity that can be sold back into the power grid. The studies found that a biomass-fueled cogeneration option would be more efficient and economical than the current system, as well as make a significant step towards SOU's carbon reduction targets. Biomass fuel typically comes from forestry byproducts, such as tree tops, limbs, and small non-merchantable logs left over from timber harvesting and from forest restoration; wood mill residues; „POTENTIAL BIOMASS PL and clean urban wood waste. 0..........I'll MTN SOU is interested in hearing community input on biomass �li �i' �, >l !% on �/ ,' r�i� ���°,�,/ r '�III �,":;,!

Burning wood biomass in efficient boilers stems CONSIDERATIONS g Y Y creates energy while helping to prevent air pollution that would otherwise come from burning slash piles,prescribed burning, and catastrophic wildfires. It also supports the local economy by providing a market for typically unused byproducts of current forestry practices. A biomass cogeneration plant would support SOU's leadership in integrating the principles of environmental,social and economic sustainability into campus planning and operations and help meet the goal of reducing campus-wide dependence on fossil fuels and greenhouse gas emissions to 10%below 1990 levels by 2020 and achieving complete carbon neutrality by 2050. IMPACTS TO Biomass also seems a good fit because of the financial benefits - the fuel is cheaper than CAMPUS AND THECOMMUNITY natural gas,which results in lower operating costs, and more alternative funding sources would be available to cover the capital cost. Alternative Approach:, Updating the Current Facility If the biomass cogeneration option does not move forward, the two outdated boilers will be replaced in the next several years with new gas-fired cogeneration units. This option would be more expensive in the long term than a biomass facility, mainly due to the rising price of natural gas,but it would have fewer impacts to campus.

SOU broadly defines sustainability as achieving increased wellbeing for humanity over time through an equitable and sustained utilization of critical natural capital. SOU's Sustainability Program collaborates across campus to improve resource conservation,increase renewable energy,reduce our carbon footprint, and provide sustainability education. The Sustainability Program is working to achieve SOU's climate goals,as outlined in the university's Climate Action Plan. These goals include: 0 By 2010,arrest the growth of greenhouse gas emissions and begin to reduce greenhouse gas emissions. 0 By 2015,achieve greenhouse gas levels that are 5 percent below 1990 levels. 0 By 2020,achieve greenhouse gas levels that are 10 percent below 1990 levels. 0 By 2050,achieve CLIMATE NEUTRALITY. Among the accomplishments of the SOU's sustainability program are the construction of the first LEED Platinum building at any Oregon public university(the Higher Education Center in Medford),the installation of solar panels on both the Ashland and Medford campuses,and a green purchasing program. And just last year,SOU became the first university in the nation to balance 100%of its water consumption. During the last year, SOU has also: 0 Installed 153 kW of solar on new residence halls (162%increase of campus solar). Campus total—247 kW of solar. 0 Received LEED Gold Certification for the new Raider Village Residence and Dining Halls. 0 Completed several upgrades and retrofits to improve lighting efficiency. 0 Received Silver Rating from the Sustainability Tracking,Assessment and Rating System (STARS) through the Association for the Advancement of Sustainability in Higher Education (AASHE). 0 Started an alternative transportation campaign with ODOT and RVTD to reduce student drive alone trips to campus. 0 Diverted more than 50% of campus waste from the landfill(through recycling, composting, and reuse). To learn more about SOU's sustainability efforts,visit www.sou.edu/Sustainable/index.html. What 'is cogeneration? Cogeneration is the simultaneous production of electricity and heat in a single system, such as a boiler and turbine-generator. Producing both heat and electricity at once is more efficient than producing them separately. Why is SOU exploring cogeneration .? Two of SOU's natural gas boilers are aging and need to be replaced. Heating and electricity needs for the SOU campus are projected to increase over time and fuel costs are also expected to rise. Experts in the field and a series of commissioned reports have recommended that replacing the current boiler system with an efficient biomass cogeneration facility that produces both heat and electricity would help reduce operating costs for the University over time and be a significant step towards the University's sustainability goals. How will SOU use the electricity generated by a cogeneration plant? The electricity generated through a cogeneration facility would be sold back into the power grid to help offset the cost of the new heating system. Electricity could also be used for some campus activities,such as electrical vehicle charging,which would also reduce SOU's carbon emissions and decrease reliance on non-renewable fossil fuels. What mis biomass and where does it come from? Biomass fuel can be made from a variety of organic materials. In Oregon,the most widely available source is woody material that comes from forestry byproducts,such as tree tops,limbs, and small unusable logs left over from timber harvesting and forest restoration;wood mill residues;and clean urban wood waste such as tree trimmings.These types of forestry byproducts will be sourced from within 30 miles of campus and chipped or ground off site prior to being delivered and stored at the facility on campus. What ® There is currently no demand for local forest residues,so the cost of biomass fuel is expected to be driven largely by production/transportation costs and rise roughly at the rate of inflation. Currently,woody biomass fuel is approximately$35 a dry ton,or about$2 per million British thermal units (BTU). In 2017,the cost of natural gas is projected to be$6.65 per million BTUs, about 3 times the cost of biomass. How does using biomass fuel affect forests and the local ® Switching to a woody biomass fuel would utilize forest residuals,which reduces waste from timber harvesting operations and precludes the need to burn slash piles in the woods. It also improves forest health and reduces risk of catastrophic wildfire by removing diseased,dead or overcrowded small trees from the forest that create added fuel during wildfires. Removing these"ladder fuels"from the forest makes it easier to prevent fires from reaching the forest canopy where they are far more destructive and harder to fight. Buying woody biomass for fuel also supports the local economy,forest industry and jobs by establishing a market for a currently unused renewable resource. Where would biomass fuel come from and whatis the long-term viability of biomass as a fuel source? Within a 30-mile radius of campus,biomass fuels are available well in excess of the needs of the proposed SOU facility. Local supplies will come from private and public forest lands and local timber mills. Studies have shown that there is greater than 100,000 BDT (bone dry tons) of biomass fuel available annually in the southern Oregon region,multiple times the 21,000 BDT required by the proposed plant annually. Could SOU's biomass cogeneration plant use residential timber waste as a fuel ® Yes,depending on the type of wood fuel,it's possible that the SOU biomass cogeneration facility could accept other types of wood fuel, such as Christmas trees,downed limbs and trees or other unwanted wood from area neighborhoods. It would have to be clean and untreated and would need to be chipped off campus. capitalWhat are the The total capital cost for a biomass system is estimated to be$12.2 million,but that amount would be offset by various $3,500 grants and tax credits available to biomass ������������������������������000$3, Current Natural Gas system projects in Oregon,which could make ---- Biomass Cogeneration System the net capital cost$7 million.The capital o $2,500 Natural Gas Cogeneration System cost for a natural gas cogeneration system $2,000 would be approximately$8.5 million.

However,both natural as g $500 options would be more expensive in the longterm than a biomass facility,mainly $0 Y due to the rising price of natural gas (see graph). Electricity produced from either system could be sold back to the power grid to offset capital construction costs.A biomass system would also earn Renewable Energy Credits that can be sold. Is it possible to use a hybrid system that utilizes both biomass and natural ® Technically,this is possible;however,this wouldn't be a viable option for SOU because the University plans to keep two of the newer natural gas fired boilers to use as a back-up heat source during high demand.While a biomass boiler could also burn natural gas,it would be foregoing the fuel cost savings. What 'is the volatility 'in the price of biomass in comparison with natural gas? Supply and demand for commodity natural gas are volatile,and the price has fluctuated dramatically in recent decades.When gas is unavailable, diesel would be used as a backup. Biomass is readily available within the region.There are numerous potential suppliers that currently produce woody biomass from lumber mills and private and public forest lands. What ® ® Biomass combustion is commercially proven technology with hundreds of installations throughout the US. It is anticipated that a facility such as the one SOU is considering would have a useful life of about 50 years. How do the fuel sources compare 'in regards to emissions and residuals? • Renewability/Sustainability:Biomass is a renewable,carbon neutral fuel,in comparison to natural gas which is a non- renewable,carbon-intensive fossil fuel.To be considered carbon neutral for the long term,however,the biomass must be harvested in a sustainable manner. • Carbon neutrality: Biogenic vs. geological: The carbon contained in biomass fuel is �� �e i� � �N � � Ca b, °transfers, from considered"bio enic"since it is already in circulation between the land,oceans and atmosphere.The carbon in natural J gas is considered geologic since it has Am, 00101 been locked away underground and is only Y released above ground by the combustion ,,, ,. of the gas, adding to the total already circulating in the atmosphere. • Particulate emissions:Natural gas,when combusted, emits very low levels of particulate matter. Biomass emits much more particulate matter,but can be controlled with sophisticated pollution 1%iog,enic, turbo i,�, r of a,re,la o�e� �,, control devices,such as those proposed for ra :i to,aatri,,I,Osspther�t CO.,Ic .A°"only°p i,at4:the,i a tItyc'"I e,il" 'i �l ��b'� 't.

The Medford-Ashland Kt� way ���� c rbon i,/,,n"t,,,o,tl,ip-.,at',MO�.4,3h.,el,"'le area has very stringent requirements for new sources of particulate matter and the proposed biomass plant can meet those requirements. The controlled biomass cogeneration facility emits only about 1% or less of the particulate matter per unit of fuel burned than a wood stove or open fire. • Ash residual:Ash produced in biomass combustion operations is captured and can be used as a low-grade fertilizer for agriculture or combined with other organic materials as a soil amendment.Natural gas cogeneration does not produce any type of ash. How much water will be consumed by the biomass cogeneration plant® operations?Recent modeling shows that the biomass boiler would need 40 gallons per minute(gpm) of water, and discharge 9 gallons per minute to the city wastewater system. There are potential alternate designs that are more expensive and less efficient,but could reduce the water use to approximately 3 to 4 gpm and wastewater to 1 to 2 gpm. cogenerationHow do the two A biomass plant would require an additional two to three staff members,as well as training of current staff.The natural gas cogeneration system would be operated by the current staff member with little additional training needed.In addition,the biomass plant would generate perhaps an additional 8 to 10 jobs in the fuel supply network. How could SOU mitigate or offset the increased particulate emissions created by burning woody ® ® The biomass plant particulate emissions from the proposed facility will be below the threshold requiring emission offsets within the Medford-Ashland Air Quality Maintenance Area. However,SOU may consider partnering with the Department of Environmental Quality(DEQ) to implement incentives for changing uncertified wood stoves for those that are certified and produce less particulate emissions. If SOU was to sponsor an offset program to exchange conventional wood stoves,the boiler's particulate emissions could be fully offset by converting roughly 20 conventional wood stoves to certified pellet stoves or roughly 50 catalytic wood stoves. Initial calculations show that perhaps less than three dozen stove changeovers would be required to balance the plant emissions of particulate matter in the winter.Without mitigation,the SOU biomass cogeneration facility would be adding 1.1 pounds of particulate mattter to the atmosphere for each hour of full load operation.It is worth noting that some of the fuel combusted in the biomass boiler would likely have been open burned in slash piles with much higher particulate emissions, so it is possible the overall particulate emissions will be less. What are the anticipated impacts for the surrounding neighbors of a biomass cogeneration plant? Location and size:Biomass systems are larger and require covered space for fuel storage,so a new facility would be built at the location of the current maintenance yard,just northwest of McNeal Hall. Truck routes and size of trucks carrying fuel:It is believed that the fuel delivery plan will keep truck traffic,noise levels, and visibility of the operations to modest levels. Noise: Fuel unloading will also generate a modest amount of noise consistent with current maintenance yard operations. Even though the operation will be 24/7,plant noise levels will be modest compared to background noise. This will be verified,in advance,by a noise study. • Odor:No unusual odors will be emitted from a biomass cogeneration plant. Aesthetics, architectural design and height of stack:A biomass cogeneration facility would have to meet the City of Ashland building and land use requirements for height and setbacks. If the community supports a biomass cogeneration facility and SOU moves forward with this option,the next step would be hiring an architect to create designs. What are the anticipated impacts for the surrounding neighbors of a natural gas cogeneration plant? • Location and size: It may be possible to house the natural gas cogeneration plant at the existing facility,though a building expansion would be necessary because the footprint needed for a cogeneration facility is slightly larger than the current natural gas plant. • Aesthetics, architectural design and stack:Any new facility or expansion would have to meet City of Ashland building and land use requirements. The building design would be consistent with the existing facility. • Noise:Noise levels for a gas cogeneration system would somewhat increase from the current boilers,but this can largely be mitigated by enclosing it in a building. • Odor:No unusual odors would be emitted from a natural gas cogeneration facility. • Aesthetics, architectural design and stack:Any new facility or expansion would have to meet City of Ashland building and land use requirements. The building design would be consistent with the existing facility. Conservation Commission Recommendations for a Climate and Energy Action Plan for the Community of Ashland, Oregon February 18, 2 015 Background: Climate change poses a severe threat to the health, safety and livelihoods of current and future residents of Ashland,as well as people around the globe. Climate change also severely threatens the natural world and the resources we depend on.We are already feeling the impacts of climate change at the local level.Without emissions reductions, severe drought,floods,and wildfires are all expected to worsen and accelerate over time. Local impacts are already being felt,including a lack of snow and loss of revenue at Mt.Ashland;water restrictions during severe drought, such as those in 2014; and smoke from forest fires affecting the tourist industry when plays are cancelled and rivers are closed for rafting. By reducing emissions locally we can contribute to preventing increasingly severe impacts. Because many changes are inevitable due to gases already emitted,we also need to prepare'our community for the changes ahead.The community of Ashland,with its strong history of conservation and a population engaged in the issue,is poised to take truly meaningful action on this extremely important issue. State Level Efforts and Policies: In 2004,the state of Oregon passed a resolution to combat climate change by setting short and long term targets for reducing greenhouse gas emissions statewide.The state has goals to reduce emissions by 10%below 1990 levels by 2,020 and 75%below 1990 levels by 2050.A recent report(Oregon Global Warming Commission 2013) shows that progress has been made and our state is on a trajectory to meet its targets,but that success is tenuous and sustained efforts are not yet in place. Success at the state level relies heavily on actions taken at the:local level. See Appendices I and II for more information on state and local actions. Why our community needs to take action:As climate''change has progressed unabated and new scientific evidence has become available,the urgency of immediate and forceful action has become increasingly clear.The state will not be able to meet its short and long term goals without action on greenhouse gas (GHG) emissions at the local level. Many communities in Oregon are already taking action to reduce emissions. Because of this,there are numerous plans and frameworks that Ashland can model its efforts after, reducing the investment in planning and moving more quickly to action.Action on climate change provides numerous benefits besides greenhouse gas emissions reductions -it also provides cleaner air and water,locally sourced energy that creates a stronger local economy, and monetary savings for residents that conserve energy. In addition to GHG emissions reductions,the community needs to become more resilient in the face of increasing likelihood of extreme events such as heat waves, drought, severe wildfire and floods.Addressing community vulnerabilities and developing cross-sector strategies are both vital for increased community resilience. Goals of a plan for Ashland: 1. Conduct a highly collaborative cross-sector effort on climate change, driven by a City/Citizen Oversight Group,who are in turn supported by a Technical Advisory Committee and Project Team (Appendix III); and with extensive community input, engagement and ongoing educational outreach. 2. Develop a Climate and Energy Action Plan for the Community of Ashland (including city operations as well as all residents,businesses,schools,and others)that includes greenhouse gas emissions targets, specific goals andstrategies, an implementation plan,timelines,and monitoring requirements for reducing GHG emissions throughout the Community of Ashland. 3. Identify risks and vulnerabilities of a changing climate to the community and resources of Ashland; develop,prioritize,and implement strategies to protect the community from climate change impacts. 4. Participate in regional efforts to reduce emissions across jurisdictions,including city and county. Specific sectors to be addressed: ➢ Infrastructure ➢ Land use&Transportation ➢ Economics &Tourism ➢ Consumption&Waste ➢ Renewable Energy&Energy Efficiency ➢ Health&Social Services ➢ Food&Agriculture ➢ Natural Resources 1 Scope: The Community of Ashland, City Operations,the Ashland watershed and other areas of influence. Timeline: Planning to begin in spring of 2015 with implementation of initial actions to begin no later than spring 2016.The plan will continue to be revised over time to include more adaptation strategies and update mitigation strategies,as needed. Resource needs:At least 0.5 FTE staff time or equivalent in contracted assistance to manage the development of the Climate Action Plan.The project manager should have expertise in community organizing and greenhouse gas emissions reductions. Steps: 1. Greenhouse Gas Inventory-The City conducts or contracts a greenhouse gas inventory that includes a subset for city operations (transportation is included); this inventory will also benefit the city operational sustainability plan that has already been adopted by City Council.The purpose of the GHG inventory is to identify local sources of GHG emissions so we can direct resources in the most efficient and cost-effective manner possible. 2. Leadership-Appoint a local Oversight Group,which will create an Advisory Committee to set scientifically valid GHG emission goals,engage community members, interface with ether groups, conduct outreach,guide strategy development,and prioritize actions. The Project Team.will support the Oversight Group as needed. See Appendix III for more information. 3. Set Emissions Reduction Targets- Many communities''use targets set by state government,while others decide on more stringent targets for their community.The Advisory Committee will investigate and decide on appropriate targets for Ashland. 4. Public Outreach- Hold a public kick-off event that informs community members about the effort, engages them on the issue,collects their input on areas of highest priority,and showcases positive stories and successes in energy savings and renewable energy. S. Engage Local Experts - Convene sector specialists to develop initial lists of strategies and prioritize them in a collaborative manner,based on cross-sector discussions of synergies,short-vs.long-term goals,areas with the greatest/fastest potential energy savings,most vulnerable resources and populations,and issues of equity and local values. 6. Consult with Council and City Staff- Hold a working session with City Council and City Staff to further refine and prioritize emissions reduction strategies and climate change preparedness strategies. City to identify'a number of actions for immediate implementation. 7. Finalize the Ilan-The plan should include emissions targets,a timeline,high level goals, specific strategies,and actions that are organized by short and long term implementation horizons.The plan should include an implementation plan that specifies who is responsible for specific actions,a monitoring plan to assess progress,and periodic updates to the plan. 8. Get Feedback- Hold an open forum workshop(s) to share information and collect feedback.Also use online forums,local TV and radio, printed media,and other outreach tools. Report the results online in other venues,as appropriate,with recap of the process, detailed strategies,and timeline. 9. Implement Implement strategies in phases,following implementation plan. 10. Assess performance- Measure and report on results periodically(every 1-3 years) 11. Reassess- Revise based on new information,ongoing trends,new technologies,and results from monitoring. Develop additional measures to protect the community from climate change impacts. 12. Educate- Continue with public outreach and education for sustained efforts. 2 Appendix I — Roadmap 2020 In 2010,the Oregon Global Warming Commission developed the Roadmap 2020 with recommendations on how to meet its 2020 greenhouse gas emissions goals and get a head start on its 2050 goals. Six technical committees were convened to address actions in specific sectors (energy/utilities, industry, forestry, agriculture, materials/waste management, and transportation/land use). Recommended actions came from each technical committee as well as additional "integrating"actions that work across sectors. Some key actions included: • Work with state agencies and local governments to conduct greenhouse gas inventories across the state • Advocate for a carbon price signal across goods and services,through an emissions cap or a carbon tax • Reduce (prevent) waste of food at the retail and consumer level by 5 • Ramp down emissions associated with coal generation • Provide financial incentives to reduce lifecycle building-related greenhouse gas emissions by 80% • Eliminate reliance on a gas tax for funding transportation infrastructure • Develop new funding streams to support climate-friendly transportation options, including high speed rail from Eugene to British Columbia.. • Encourage agricultural practices that increase carbon sequestration in soils • Prepare the agricultural industry for reclining reliability of water resources For more information on the Roadmap 2020 and the full report go to this link (http://www.keeporegoncool.org/content/roadmap-2020). For the third biennial report (2013) to Legislature from the Oregon Global Warming Commission go to this link (http://WWw.keepor''e'goncool.org/v,i,ew/ogwc-reports). 3 Appendix 11 o Review of Climate e s The Climate and Energy Subcommittee of the Conservation Commission reviewed numerous Climate Action Plans from other communities. We found certain aspects of the different plans to be informative in our efforts to develop strategies for Ashland.We have listed plans that we think are good examples in Table 1, along with some of their more outstanding features (in bold). • Mitigation refers to reduction in greenhouse gas concentrations in the atmosphere in order to reduce the overall magnitude of climate change. Effective mitigation requires concomitant emissions reductions throughout the U.S.and other key nations,as well as increased carbon uptake in forests. Mitigation is needed to protect people from the most severe impacts over the long term. • Adaptation refers to actions taken to protect people and resources''from the impacts of climate change.As climate change is already being felt and impacts will worsen for decades based on emissions already released,adaptation is needed along with mitigation.
