In addition to the obvious damaging effects of polluted air upon human health and welfare, there are the less obvious and irrepar- able effects on our eco-system. All in all, these negative effects have resulted in a general lowering of the "quality of life." CLEAN AIR ACT In response to the nationwide concern in regards air pollution, Congress passed and the President signed the Clean Air Act of 1970. This legislation set Federal standards for six different atmospheric pollutants. In addition, each of the states was required to develop an implementation plan describing how these standards will be attained and maintained. Unfortunately a number of urban areas, including the City of Tigard, have failed to meet one or more of the required standards. The Act requires each state to designate such areas as "nonattainment areas." Currently, the City of Tigard is a nonattainment area for the primary standard for two pollutants, namely carbon monoxide: and ozone. In 1977, Congress amended the Clean Air Act and designated the year 1982 as the deadline for full compliance with Federal air quality standards. Acknowledging the difficulty in terms of satisfying this goal for carbon monoxide and ozone, a further extension (to 1987) was granted for compliance with the stipulation that the affected state demonstrate an on-going commitment to improving air quality, The Act states that the need for an extension to 1987 and the required demonstration of good faith efforts for solving air pollution problems must be documented in a State Implementation Plan (SIP).* STATE IMPLEMENTATION PLAN (Air Quality) The City of Tigard lies within the Portland-Vancouver Interstate Air Quality Mainten- ance Area (AQMA). This area is described in the draft State Implementation Plan (SIP) for air quality, published jointly by the Department of Environmental Quality (DEQ) and the Metropolitan Service District (MSD) in April, 1979. The draft SIP shows that the entire AQMA is in nonattainment for meeting the recently revised federal ambient air quality standards for ozone and is predicted to remain in non- attainment to at least 1987 unless additional control measures are undertaken. MSD and DEQ are developing a regional control strategy to bring the metropolitan area into attainment by 1987. *Summary, Air Quality State Implementation Plan for the Portland Metropolitan Area, MSD(April, 1979). __ Page 2 Since the pollutant CO is directly emitted into the atmosphere from automobile exhaust, carbon monoxide problems are almost always associated with heavily traveled raodways. The air quality analysis in the SIP revision indicates that a section of Highway 99W (Pacific Highway) in the City of Tigard is projected to violate the 8-hour carbon monoxide ambient air quality standards by the end of 1982 and through 1987. From Highway 217 to S.W. Hall Boulevard, according to DEQ research, several Tigard roads exceed federal standards for carbon monoxide during periods of air stagnation by more than 1007. Federal Standards allow for a maximum of 10 mg per cubic meter. The City of Tigard is aware of these potential problem areas and will work with MSD to better quantify the extend of these problems. GENERAL POLICIES 1. The City of Tigard will cooperate and work with MSD and DEQ in developing a regional control strategy to bring the metropolitan area into attainment by 1987. 2. Until such time as control strategies are realized, the City of Tigard will use measures described in the DEQ Handbook for "Environmental Quality Elements of Oregon Local Comprehensive Land Use Plans" when planning any development activities having the potential to directly (by direct emissions) or indirectly (by increasing vehicular travel) affect air quality. Introduction (Water Quality Management) The effects of various pollutants in stormwater runoff on streams and other natural waters is receiving greater attention than ever before in the United States. As more point sources of pollution are identified and treated, they create less impact on receiving waters. Nonpoint sources such as stormwater runoff are having progress- ively more relative impact, because little or nothing is being done to control them. Hence, completing the work of controlling water pollution will require attention to s`tordmiater runoff and other nonpoint sources. Essentially pure as it condenses in the upper atmosphere, rainwater accumulates particulate matter gases, and odors as it falls through the air. As rainfall reaches the ground, particulates are first picked up and then carried away as overland flow occurs. Urban runoff can include a wide variety of organic and in- organic pollutant materials, and these may significantly alter the oxygen content in local streams. Among the materials found in urban stormwater runoff are con- struction and erosion sediment, air pollution fallout, vehicular petroleum dripp- ings, vehicular emissions containing heavy metals, chemical fertilizers containing nitrogen and phosphorus, animal droppings and leachate from leaves and decaying organic material, pesticides and herbicides.* * Technical Sup lement 3, Water Qualms Aspects of.

Low historic flows, irrigation runoff and use, increased development pressure, and industrial effluents contribute to the river's poor water quality. In the past the river has had no observable flow in the summer months, becoming polluted and highly eutrophic with total fecal coliform courts ranging from 60 to 7,000 mpn (most probable number). Currently several dam and reservoir projects are under consideration for the Tualatin River and it's tributaries which could augment summer low flows and improve water quality. However, planning for these reserviors is in the embroyonic stages and development seems doubtful. FANNO CREEK In the past, Fanno Creek has been heavily polluted due to point and noapoint sources. During the summer months BODS rose to nearly 4 mg/1 below the Fanno Creek plant, almost doubling the instream concentrations above the plant. i i All treatment plants discharging into Fanno Creek and tributaries have been abandoned since 1976 (replaced by the Durham plant), which has aided water quality considerably. However, it is possible that extremely low summer flows in these tributaries; coupled with increasing urban runoff as the area develops, will stand in the way of achieving water quality goals. WASTE TREATMENT MANAGEMENT CO24PONENT AND 11208"' Y The City of Tigard recognizes and assumes its responsibility for operating, planning, and regulating wastewater systems as designated in MSD's Waste Treat ant Management Component. Y Sa, Exhibit "B" ENERGY CONSERVATION GOAL 13 Introduction The United States relies on oil and natural gas for 75% of its energy use. Recent energy studies indicate that proven oil reserves in the world could be depleted by 1990 a.£ lower consumption is not achieved. Moreover, if energy consumption con- tinues at present rates, yearly average electricity use could increase by almost 200% by the year 2000. Sufficient generating capacity to meet this demand is, by all means, not certain. In the Northwest, the Bonneville Power Administration will not be able to guarantee the availability of sufficient power from its hydro system to meet all firm energy needs after 1983. Increased energy demand could exceed assured supply unless a strong local commitment to energy conservation and energy source diversification is made. At the same time, energy costs to the area's users could escalate very rapidly. Furthermore, if energy demand continues to rapidly increase, there is no guarantee that there will be sufficient capacity to meet that demand at any cost. The need to conserve energy has promoted a number of responses on the national, state and regional levels. The National Energy Plan includes an "immediate objective," a "medium-term objective" and a "long-term objective." These objectives are: 1) "to reduce dependence on foreign oil and vulnerability to supply interruptions," 2) "to keep U.S. imports sufficiently low to weather the period when world oil production approaches its capacity limitation," and 3) "to have renewable and es- sentially inexhaustible sources of energy for sustained economic growth." The energy conservation goal of the Oregon Land Conservation and Development Com- mission (LCDC) requires local jurisdictions "To conserve energy--- Land and uses developed on land shall be managed and controlled so as to maximize the conservation of all forms of energy." The transportation goal of LCDC requires that a transportation plan shall "minimize adverse social, economic and environmental impacts and costs" and shall "conserve energy." CRAG REGION ENERGY ANALYSIS 1n September, 1976, the Board of Director of the Columbia Region Association of Governments (MSD) adopted energy conservation Objective IV for the purpose, as stated in the Goals and Objectives and Implementing Rules, "to give structure and direction to regional planning consistent with the adopted Statewide Land Conserva- tion and Development Commission (LCDC) Goals and to implement CRAG's statutory responsibility." The CRAG substantive objectives relating to energy conservation are: 1. Support of Land Use: The conservation of energy shall be maximized an the development and redevelopment of the land and uses on the land. 2. Renewable Energy Sources: Development of energy consuming activities sha11 minimize the use of energy from renewable energy sources, based on sound economic principals. t - The potential for energy conservation is tremendous. It has been estimated that Americans ii. 1975 wasted more energy than was used by 2/3 of the worla's population. Conservation, therefore, could significantly reduce the rate of consumption of non-renewable sources of energy and save millions of dollars. Conservation and fuel efficiency are the cornerstone" of the National Energy Plan. According to this plan, "Conservation is cheaper than production of new supplies, and is the most effective means for protection of the environment." Damage to the environment can result in very high energy costs in the form of costly correction measures. For example, in land development, excessive environmental manipulation can be avoided by working with the natural landscape. The importance of energy conservation cannot be overemphasized. Conservation would reduce the possibility of shortages in energy supply and the rate of future energy price increases. It would strengthen the economy and prevent the loss of jobs. It would help protect the environment and individual choice. It would reduce govern- ment expenditures on energy and protect low-income groups from energy price increases. At the same time, it would require only minor lifestyle changes. Conservation buys time in which to develop new energy sources. Programs such as home weatherization would produce immediate local benefits due to reduced energy expenditures by the homeowner or renter and the creation of new jobs. It has been estimated that electric energy made available through conservation is six times cheaper than energy provided by new thermal power plants. ENERGY USE CHARACTERISTICS - TIGARD* The City of Tigard is reliant upon electricity for 22 percent (22%) of its residential energy requirements, natural gas 20 percent (20%) and fuel oil 58 percent (58%). Electricity is the predominant fuel for space heat and is also used to provide hot water to 88 percent (88%) of all households. Both single (2.98) and multiple (1.83) family household size tends to he less than the county average, while gross household income distribution is slightly more than Washington County community average. The majority of both single and multiple family dwellings were built since 1950. GENERAL POLICIES 1. The City will work with federal, state and regional agencies to promote energy conservation. 2. The City will encourage energy conservation through land-use planning and site and building design review. 3. The City will encourage community education on domestic conservation methods. 4. The City will promote energy conservation in construction practices in the City. 5. The City will encourage more efficient transportation systems.
