1. "A Decade of Emission Dioxin Data"

Al Lanfranco, A. Lanfranco and Associates, Delta, B.C.

This paper will discuss the techniques involved in the preparation and collection of organochlorinated substances (primarily dioxin and furan) from stacks and emission sources associated with various combustion processes. The presentation will largely be related to case studies of over 150 emission tests from more than 30 sources between 1990 and 2000. Some of the sources have had as many as 20 or more individual tests performed. The case studies range from PCB Incineration in Indonesia, biomedical incineration studies in Hawaii, and power boiler combustion in Coastal B.C.

The processes to be discussed include woodwaste power boilers, recovery boilers, MSW incinerators, hazwaste incinerators, biomedical incinerators, cement kilns, woodwaste gasifiers, and landfill gas incinerators. Fuel types, emission control equipment and process variables are discussed with respect to the impacts and advantages of specific process operating conditions.

The presentation includes discussions of Canadian and EPA standards and the differences in sampling and analytical protocols. QA/QC procedures, analytical detection limits, toxic equivalency, and costs are presented.

Comparisons of similar process units (boilers) and the use of surrogate parameters in predicting dioxin levels are also discussed.

Alan Lanfranco graduated from BCIT in 1971; in the first graduating class of Environmental Engineering Technology.

Al’s career began at Inco, in Thompson, Manitoba where he conducted analysis of air and water samples. In 1974, Al joined Beak Consultants in Vancouver as an emission monitoring technologist.

This paper presents a discussion of the various ways detection limits can be calculated and presented when preparing source test data. It emphasizes the importance and benefit of pretest planning to determine what the detection limit will be in the stack gas and how to present non-detect data so it doesn’t skew models or risk assessments to a conservative result. Physical factors that influence detection limits in stack gas sampling are discussed, including selection of laboratory analytical methods and sampling procedures and stack conditions. Methods of presenting data versus each type of detection limit handling style are also discussed.

3. "Experimental Development of a VOC Emission Factor for a NESHAP Compliant Paint Stripping Material (When MSDS Information & Material Balances are not Sufficient)"

Stacia G. Dugan, Environmental Engineer

CH2M HILL, Bellevue, WA

The purpose of this aerospace compliant stripper emission evaluation was to develop a volatile organic carbon (VOC) emission factor for chemical stripping of paints from aircraft at a military base. The current emission factor for the stripper was provided by the stripper manufacturer and assumed 25% of the weight of the stripper used was emitted as a VOC. The manufacturer derived the emission factor from evaporation studies conducted on the stripper. The results from this type of test tells us how much material evaporates, not the amount of volatile organics emitted. Corrections to the evaporation results for water and peroxide content of the stripper can be made, but this does not account for the potential oxidation and evaporation of non-volatile organics. It also does not account for the organic portion of the evaporative emissions with respect to the normal stripper usage timeline. Complete evaporation to dryness does not occur during normal use of the stripper.

Ideally, the stripper material needed to be tested while stripping a painted surface under controlled environmental conditions, with constant monitoring of the weight loss and the VOC concentration of the vapor from the stripping process. A laboratory bench scale test was conducted on the stripper applied to painted aluminum aircraft panels. Results of the bench scale stripper tests were used to derive an emission factor for the stripper.

The emissions from the activity were measured by EPA Method 25A for total hydrocarbons (THC). Total hydrocarbons emissions as measured by EPA Method 25A are often used to represent Volatile Organic Compound (VOC) emissions, especially with mixtures of organic emissions. This emission factor evaluation produces a lower emission factor than the original assumptions. This may be important to sources when completing emission reports to regulatory agencies, when paying fees on those emissions, and when considering sources which may be included in control technology considerations for non-attainment area planning.

Optical Scientific, Inc., 205 Perry Parkway, Suite 14, Gaithersbury, MD, 20877

Airflow sensing in an industrial environment is a difficult challenge. Existing technologies like ultrasonic and Pitot tubes are expensive, require significant maintenance and installation costs, and can suffer from nonrepresentativeness leading to a misreporting of mass flow. For example, Pitot tube devices only measure at one point and may under or over report the true flow. And ultrasonic devices must be installed a 2 levels on the stack leading to high installation costs.

The optical anemometer was designed to solve these problems. Optical flow sensing was approved in 1998 as an equivalent Method 14 technology for compliance with the MACT rules. More than 40 optical anemometers are installed at primary aluminum producers around the world. The OFS-2000 Optical Flow Sensor is the latest introduction in the product line and was designed for measuring in the relatively short diameters of stacks and ducts.

The optical anemometer is installed at one level and measures thorough glass windows across the stack or duct. This means that installation costs are low and product life is long since the measurement is non-contact. True representativeness of the data is assured due to the path-averaged nature of the measurements and verified by thorough testing at the National Institute of Science and Technology (SIXT) Wind Tunnel and a 837 Mw generating station at Potomac Electric Power company (Pepco) for 40 CRF Part 75 compliance.

Ponderay Newsprint Company operates a newsprint mill in Usk, Washington. A Predictive Emissions Monitoring System (PEMS) for boiler NOx emissions was implemented at this mill in September of 1999. PEMS work by accurately predicting NOx emissions based upon more easily measurable variables, such as air flow into the boiler, temperature of the combustion air, fuel flow, residual oxygen concentration in the stack, etc. This application will save the mill in emissions monitoring costs.

First, conventional Continuous Emissions Monitoring System (CEMS) measurements were performed, providing historical data over a wide range of operation. Then an empirical predictive model was created from the historical data, and the model was put on line. To qualify to replace the CEMS, the NOx PEMS was subjected to rigorous certification testing as outlined by the U.S. Environmental Protection Agency (EPA). After review, the EPA certified the PEMS for operation, and the CEMS was removed from the mill. Re-verification of the predictive model will occur yearly with a relative accuracy test.

In addition, statistical data reconciliation techniques were employed to identify sensor failure, notify operations, and replace the bad input value with a predicted value in order to continue PEMS calculations. Sensor failures were simulated, and the EPA approved the PEMS for operation during single sensor failure.

Major new sources and major modifications to stationary sources of air pollution are required to undergo review through the prevention of significant deterioration (PSD) program. This review may involve predicting the impacts of the proposed source / modification to Class I areas, including criteria pollutant concentration, visibility impairment, and acidic species deposition. Currently available Gaussian, steady-state plume models, such as the Industrial Source Complex (ISC) model, are not well suited to estimate visibility and deposition impacts to Class I areas, particularly at distances over 50km.

CALPUFF, a LaGrangian dispersion model, is well suited to predict impacts to Class I areas, even at large distances (~ 200km). It includes modules that incorporate atmospheric chemistry and physics, allowing it to directly calculate visibility and deposition impacts. CALPUFF can also incorporate temporally and spatially variant meteorological conditions throughout the modeling domain, allowing for more realistic treatment of the atmosphere than Gaussian models. The development of three model scenarios for the same stationary source using CALPUFF and different types of meteorological data (single-station, MM4 derived windfields, and MM5 derived windfields) are discussed. Techniques and "how-tos" are presented, focusing on non-research users.

Major new sources and major new modifications to stationary sources of air pollution are required to undergo review through the prevention of significant deterioration (PSD) program. Part of this review may require predicting the impacts of the proposed source / modification to Class I areas, including visibility impairment and acidic species deposition. As described in a previous paper, this analysis may be accomplished using the CALPUFF model.

A single stationary source complex was modeled in CALPUFF using three different sets of meteorological data: A single surface station, surface stations combined with MM4 mesoscale meteorological model output, and surface stations combined with MM5 mesoscale meteorological model output. Model results are compared and discussed within the context of performing the Class I analyses. Implications for choosing the most appropriate model application are discussed.

Positive matrix factorization (PMF) was applied to the chemical elements analyzed from a total of 1261 daily PM2.5 samples collected at a residential site in Spokane, WA from 1995 through 1999. Samples were obtained from a versatile air pollution sampler and included 45 particulate elements as well as organic and elemental carbon. Due to the relatively low concentrations of sulfate compounds, it was not necessary to adjust the PMF solution for the ubiquitous presence of these compounds. Preliminary results indicate that 6 sources contribute independently to the observed mass. Those sources and average mass contributions are vegetative burning (41%), secondary aerosol (24%), vehicle emissions (15%), airborne soil (8%), municipal incinerator (3%), and metal processing (2%). Potential source contribution functions (PSCF) were computed using hourly weighted wind profiles and estimated mass contributions from each source. The results of PSCF analysis agree well with the reported locations of the point sources. The correlations between the estimated source contributions and concurrent gas phase pollutant concentrations were also consistent with the identified source categories - carbon monoxide was highly correlated with the vehicle source and sulfate and nitrate collected on the denuder upstream of the filter were highly correlated with the secondary aerosol.

Kevin Downing

Gasoline is loaded onto barges in the Portland/Vancouver harbor for transport within the harbor, to coastal ports and to destinations elsewhere on the Columbia and Snake Rivers. Gasoline vapors escape during loading resulting in annual emissions of over 600 tons per year of ozone precursors. In the most recent emission inventory (1992) barge loading accounted for more than 1 percent of total anthropogenic volatile organic compound (VOC) emissions. When the state of Oregon first adopted VOC control standards in 1978 barge loading was proposed for control standards but action was deferred pending resolution of safety concerns. Since then barge loading has remained uncontrolled because of additional unresolved issues related to jurisdiction, technical feasibility and financial cost. Barge loading was again identified as a significant source of ozone precursors in the 1996 Portland ozone maintenance plan but proposals for controls were deferred pending construction of the cross-Cascades pipeline. Operation of this pipeline was projected to reduce marine loading activity and emissions by 90%. But by early 1999 the pipeline was several years behind schedule and Oregon DEQ began a rulemaking process to gain the projected emission reductions through marine loading vapor control requirements. Based on a RACT-like analysis, regulations were adopted calling for a 95% reduction in emissions for all Portland terminals including the smallest terminals loading about 100,000 barrels a year.

Before receiving permit approval to flare gas intermittently from a well, oil and gas companies are required to assess the potential environmental impact of flare emissions. Recently the British Columbia government has requested the assessment include model predictions of potential vegetation damage. In addition, the provincial government will place restrictions on the meteorological conditions during which flaring may take place.

During the past year dispersion modelling was carried out for sour gas wells (>5% H2S). The model results often show significant areas where the ambient SO2 concentration exceed provincial guidelines and where there is a potential for vegetation damage.

One difficulty with pre-flare modelling is that the available meteorology is often not representative of the area of the well site. Meteorological monitoring stations are normally set up shortly before flaring takes place and consequently the post-flaring assessment can use local meteorological data.

The post-flaring assessment of up to six cases will show that the impact from the flare is normally less than the pre-flaring model predictions suggest and that potential vegetation damage is minimal. The implications of these findings on pre-flaring modelling and regulatory restrictions on flaring conditions will be discussed.

This paper is part of a comprehensive 3-year exposure assessment study that is examining the PM exposures and health effects in individuals with chronic obstructive pulmonary disease (COPD) and cardiovascular diseases. This determines the relationship between personal, indoor, and outdoor PM exposures among COPD subjects and healthy controls in the Seattle area. Forty-six COPD and healthy subjects living in private or group homes participated in the monitoring sessions in the fall of 1999 and the winter of 2000. Personal, indoor, and outdoor PM10, PM2.5 and CO were monitored for 10 consecutive days for each subject. Harvard impactors (HI) were used for PM2.5 and PM10 measurements at indoor, outdoor, and central sites, while Harvard personal environmental monitors (HPEM) were used for personal PM2.5 monitoring.

Duplicates of the HI2.5 were collocated with the Federal Reference Method to determine its accuracy (R2 = 0.98, slope = 0.95, p < 0.001, n = 27 pairs). The coefficient of variation for the HI2.5 was 5.1 percent. The relationship between PM2.5, PM10, and CO concentrations at home indoor, home outdoor, and central sites was determined. The representativeness of the central site measurements for those at the home sites was also determined. The average daily PM2.5 outside the individual home sites was significantly correlated with PM2.5 measured at the central site (R2 = 0.92, slope = 1.00, p < 0.001, n = 22). The home indoor and outdoor levels of PM2.5 were also correlated (R2 = 0.20, slope = 0.42, p < 0.001, n = 126). However, personal exposures to PM2.5 were poorly correlated with indoor PM2.5 (R2 = 0.06, slope = 0.61, p = 0.01, n = 108). Preliminary results indicate that indoor CO was significantly correlated with the average fixed site CO concentrations (R2 = 0.19, p < 0.05, n = 24).

Elevated levels of PM2.5 are associated with increased rates of hospitalization and respiratory death in elderly individuals with COPD. To determine whether PM2.5 levels are associated with alterations in oxygen saturation or heart rate in elderly COPD subjects, we performed daily measures of pulse oximetry on 45 elderly individuals with and without COPD who were participating in an air pollution exposure study in Seattle. Participants were monitored on 10 consecutive days between October 1999 and March 2000. Results: The average age of participants was 76. The COPD subjects had a median FEV1 of 54% of predicted value. The oxygen saturation levels in the 22 COPD subjects ranged between 81 and 99%. Personal PM2.5 levels ranged from 1.03ug/m3 to140.44 ug/m3, median 16.8ug/m3. The heart rate and oxygen saturation data was paired with exposure measures to determine the intra-individual change in physiologic measures relative to personal pollutant exposure levels. Univariate analyses using a generalized linear model with random intercept demonstrated no significant association between personal PM2.5 levels and oxygen saturation (p=0.51) or pulse rate (p= 0.47) in the COPD subjects. Furthermore, an analysis of fifteen participants with 02 saturations < 92% was unable to detect an association between PM2.5 levels and intra-individual alterations in oxygen saturation. Conclusions: Our study was unable to detect an association between ambient levels of PM2.5 and changes in heart rate or oxygen saturation in a susceptible elderly population with COPD.

In 1998, the Puget Sound Clean Air Agency (Clean Air Agency) undertook a stakeholder process to develop implementable, cost-effective strategies to reduce PM2.5 in the central Puget Sound basin. This paper summarizes the history of the stakeholder involvement process beginning with the recommendations of the Clean Air Agency's Health Committee that the Agency strive to reach a stringent PM2.5 air quality goal. The authors review the structure and design of the stakeholder process including who was involved and how the stakeholders were selected. In addition, the paper describes the process used to share technical and policy options with the stakeholders and how stakeholder feedback was used to guide the process. To illustrate this process, the authors summarize the role of technical "white papers", evaluation criteria and smaller working group input to the larger group process. The paper concludes with a summary of how recommendations were developed by the group, how differing opinions by stakeholders with divergent views were addressed and how these recommendations have been incorporated into the Clean Air Agency's strategic planning process.

In 1999, the Puget Sound Clean Air Agency undertook a Stakeholder Process to develop cost-effective strategies to reduce PM2.5 in the central Puget Sound basin. The presentation will contain support information used in the process to determine the major source categories of PM2.5 and the potential effectiveness of implementing the high-priority emission reduction strategies. The support data includes emission inventory estimates, source apportionment results and projected effects on air quality and visibility. Emission inventory estimates and source apportionment results identified indoor and outdoor burning, motor vehicles and industrial sources of SO2 as major sources of PM2.5. High-priority emission reduction strategies addressed these sources. Estimates of emission reduction strategy effectiveness showed that implementing the first and second tier emission reduction strategies would result in meeting the Health Goals recommended by the agency’s PM Committee. These recommendations were an annual goal of 15 ug/m3 and a 24-hour goal of 25 ug/m3. Both of these goals are "never to be exceeded".

The subject of this project is the control of emissions from an organic chemicals manufacturing plant located in the southeastern United States. The industry found itself under pressure from the surrounding community to reduce chemical odors emitted from the facility and from the local sewer authority to reduce discharges of ammonia to their sewers.

The plant, which can be classified as an organic chemicals, plastics and synthetic fibers (OCPSF) manufacturing facility, is engaged in production of styrene/butadiene and polyvinyl acrylate polymers. A flare system was originally used to control air emissions from the manufacturing processes. Effluent from equipment cleanup is pretreated in a precipitation and solids separation process prior to combining with other streams. Prior to the implementation of this project, the combined wastewater was directed to an aerated lagoon prior to discharge to the municipal sewer.

Concurrently with the wastewater and the emission control projects, a need for an additional supply of steam to the manufacturing process was identified. This required installation of an additional gas-fired boiler.

The plant management was considering three seemingly unrelated projects. The engineering contract was initially intended to address the odorous emissions and the ammonia discharges projects only. A project team was formed to develop process designs for the projects. It was concluded shortly thereafter that the issues should be addressed as a single project that would provide for elimination of the ammonia discharges, elimination of the hydrocarbon emissions, and the generation of an additional quantity of steam. An additional benefit of this approach was the recovery of the heat value of the hydrocarbon emissions. This paper provides description of the design of a single system providing for elimination of ammonia discharges and reduction of emissions while providing additional steam capacity for the production process. Design parameters and system performance is provided.

In 1999 EPA launched a joint effort with the Department of Energy and industry groups to improve environmental performance and ease regulatory burdens for the metal castings and foundry industry. Four projects were identified:

• Environmental Assistance
• New Source Review Permitting Guidance
• Reuse of Spent Materials
• Performance Incentives

The metal casting industry process involves molten metal being poured into a mold to solidify. This includes investment casting, die casting, and foundries. It does not include primary and secondary metal production, smelters, extrusion, forging, or rolling mills.

The NSR workgroup goals are to

decrease the time to fill our permit applications,

• identify when it's necessary to apply,
• decrease permit engineer's review time, and
• improve the quality of applications.

Since most operations are small businesses, the group hopes to provide guidance on minor NSR permitting also. The work products for the group will be a plain language manual on NSR permitting for the industry and a technical information guide for state and local regulators. These manuals will include information, such as, source descriptions, control technology options, permit examples, and emission factor references. A subsequent PNWIS workshop is also planned to review hooding and capture strategies in an Industrial Ventilation Design Workshop.

Findings of this workgroup process will be presented in this paper with an emphasis on New Source Review.

In February 2000, EPA created a workgroup under the Clean Air Act Advisory Committee’s (CAAAC) Subcommittee for Permits/New Source Review/Air Toxics. EPA created the workgroup to obtain stakeholder input on how to structure State/Local/Tribal (S/L/T) programs under the risk-based phase of the national air toxics program. The workgroup consisted of 21 members representing State and local agencies, cities and elected officials, an academic association, tribal authorities, environmental groups, environmental justice groups, and EPA. The Puget Sound Clean Air Agency was asked to participate and represent local air agencies. The workgroup was tasked with structuring a program to address unacceptable public health risks across the country, while striking an appropriate balance between the need for local flexibility and the need for national support for areas that require Federally mandated programs.

The workgroup identified four categories of goals to be met by an overall program to reduce air toxics risk. These are national, area-wide, near source, and community/neighborhood risk reduction goals. To meet each goal, the workgroup recommends a four-step process that includes assessment of the problem, program development, program implementation, an audit/backstop process. The EPA will consider the workgroup’s recommendations, along with public comments that were received in 1999 on the proposed Integrated Urban Air Toxics Strategy, in developing a plan for an overall program to address air toxics risk.

This presentation will include an overview of the workgroup process, the final recommendations, and critical issues identified by the workgroup.

Every year each EPA regional office enters into an enforcement Memorandum of Agreement (MOA) with EPA headquarters Office of Enforcement and Compliance Assurance (OECA). The national guidance for the MOA is the result of a collaborative effort by EPA headquarters and the national association representing state and local air directors (STAPPA/ALAPCO). The main guidance STAPPA/ALAPCO has given EPA for FY 2001 is to complete the initiatives that are currently underway before adding new activities. As a result the FY2001 priorities look much the same as the previous two fiscal years.

EPA will continue to focus on inspection and enforcement activities involving the petroleum refining, organic chemical manufacturing, iron and steel manufacturing, and pulp and paper sectors. They are particularly concerned about enforcement of federal hazardous air pollutant and new source performance standards for these industries.

   The Greater Vancouver Regional District is preparing an Air Quality Management Plan for the post-2000 period. Fine particulate has been identified as the contaminant of highest concern.

   Emission inventories for the Lower Fraser Valley show that road dust emissions are a significant source (25%) of fine particulate in the region. These estimates were calculated using the USEPA empirical equation that relates dust emissions to vehicle weight, vehicle distance traveled, and the amount of dust (silt loading) on the roads. Although the best available silt loading data was used (a limited set of measurements), considerable uncertainties remain in the estimate as silt loading can vary with location and weather conditions.

   In order to improve the estimate, an expanded program is underway to measure silt loadings at twenty streets throughout the Lower Mainland. Samples are being collected in each season from spring 2000 to winter 2001, for a total of eighty samples. This silt loading data will be used to revise inputs to the USEPA road dust emission estimation model, which will provide our best estimate of road dust emissions in the Lower Fraser Valley.

2. "Dimethysulphide (DMS) Sampling in the Georgia Strait"

   Roxanne Brewer

   Environment Canada, Vancouver

   Dimethylsulfide (DMS), which is emitted from the ocean surface, has been shown to be the largest natural source of sulphur to the atmosphere and therefore the major source of non-seasalt sulfate in aerosol particles in the marine atmosphere. Its oxidation product, sulphate, has been shown to combine with gaseous ammonia and nitrate to form ammonium sulphate and ammonium nitrate aerosols, implicated in the formation of white haze, a major factor in visibility impairment in the Lower Fraser Valley. Although a large proportion of the ammonia involved in the production of white haze is believed to originate from manure application, sulphur–rich marine biogenic emissions have not been quantified in this region. In the present study, DMS concentrations were measured in seawater at 51 stations in the Georgia Strait in November 1999, April 2000 and August 2000 and during a 24-hour sampling period at a fixed station in August 2000. Surface water DMS concentrations ranged between 0-29 nmol/L. The highest DMS concentrations were measured during the April 2000 campaign during a strong phytoplankton bloom. Concentrations were similar to those measured in other coastal areas throughout the world. The data will be used to estimate ratio of biogenic to anthropogenic sulphur emissions to the Greater Vancouver/Fraser Valley airshed.

   Roxanne Brewer is an Atmospheric Processes Scientist with Environment Canada in Vancouver. Roxanne's background is in biology and environmental science. Her past work has included environmental assessments of aquatic ecosystems. She is currently working on air quality studies under the

The lower Fraser Valley contains more than half the population of British Columbia. The vast majority of these people are located in urban centers, particularly Vancouver. However the population has spread through the Fraser Valley in the last few decades, with more change expected. As a consequence of " man’s activities" in the area and magnified by our unique geographic location, there are increasing numbers of chemicals and substances that are airborne and inhalable. These substances are largely from local sources, but there are also long-range transport phenomena that can impact our area too.

Environment Canada has been sampling the air in several locations throughout the Vancouver and lower Fraser Valley for several years. Those sampling programs have shown the presence of several substances in the air – chemicals and particles – that are of interest. Their impacts may be important to human as well as environmental receptors. However, little information is available on human exposure limits.

Wayne Belzer is the Senior Atmospheric Chemist, Aquatic & Atmospheric Sciences Division, Environmental Conservation Branch, Environment Canada. He has occupied this position for more than ten years, and has worked in both regional and national programs where he has contributed to the knowledge about substances in the atmospheric pathway.

For many years marine sediments have been recognized as a sink for a large number of contaminants that enter the marine environment. Over the last two decades, it has also been determined that the surface microlayer of marine waters can be an area of contaminant concentration, especially for chemicals such as pesticides, metals and chlorinated hydrocarbons. The surface microlayer, approximately 50 u thick, is the atmospheric interface with the aquatic environment; thus, contaminants from both atmospheric deposition and terrestrial runoff can concentrate in this layer. Toxins in the microlayer can be 100 to 10,000 times higher than in the water column below, and can potentially cause significant impacts to the eggs and/or larvae of marine organisms that utilize the microlayer as 'nurseries'. It has also been shown that tidal action can coat intertidal organisms with the microlayer contaminant concentrations. Monitoring has been conducted previously in areas such as Chesapeake Bay and Puget Sound, with elevated contaminant levels and direct toxicity measurements being recorded. The Ministry has initiated a preliminary sampling program in Burrard Inlet and other Georgia Strait waters to determine whether or not microlayer contamination can potentially impact on marine life here. A locally developed rotating drum sampler has been utilized in the last year to collect a limited number of samples. Contaminant elevations in the microlayer have been measured.

Brent Moore is a water quality biologist with the Ministry of Environment, Lands and Parks' Pollution Prevention Program in their Lower Mainland Regional Office. Over the last 25 years, he has conducted water quality studies and undertaken environmental impact assessments related to water quality, aquatic ecology and aquatic toxicology in the Lower Mainland.

Victoria, B.C.

The Air Resources Branch (ARB) of the Ministry of Environment, Lands and Parks compiles emission inventories to support national, provincial and local air management initiatives. Provincial inventory estimates for common air contaminants (CACs) are compiled through the co-operative efforts of the

Greater Vancouver Regional District (GVRD), the Ministry, and Environment Canada (EC). The first B.C. only CAC preliminary emission inventory was compiled for 1983, successive reports have built on this effort. For 1995, a complete emission inventory including permitted, area and mobile sources was produced. Much has changed and been learned since the 1983 work. Permit fee estimates are now used as a starting point for determining actual emission releases. Estimation techniques for area and mobile sources have also improved considerably. EC has primarily responsibility for compiling greenhouse gas (GHG) estimates for B.C. EC, the Ministry, and the GVRD have also completed various air toxic emission inventories for the province. The next emission inventory update is planned for the year 2000. For this, the

GVRD plans to inventory all Lower Fraser Valley (LFV) sources for CACs (CO, NOx, SOx, VOC, and Particulates with PM10 and PM2.5 breakdowns) and major greenhouse gases (CO2, CH4 and N2O). For the rest of the province, ARB will be concentrating its efforts on point sources, prescribed burning and

wildfires, and road dust. CACs will be included, as may GHGs. Estimates for the remaining sources (B.C. outside the LFV) will be compiled by EC. With increased emphasis on local air management, there is a need for producing sub-inventories for areas of the province that can be subject to poor air quality, such as populated, industrialized, mountain valleys. To fulfil this, ARB is in the process of making the emission inventory accessible on the Ministry's geographic information system (GIS).

Tony has worked with the Air Resources Branch of the Ministry of Environment, Lands, and Parks for over ten years. His main areas of responsibility are emission inventory development, industrial discharge limit setting, and manual stack sampling policy.

A substantial amount of emission inventory work has been completed under Tony's direction. He is responsible for completing provincial inventory updates for 1990 and 1995 base years. For these updates Tony has:

• served as the first provincial co-chair of the Emissions and Projections Working Group (EPWG) established under the NAICC,
• managed numerous contracts aimed at estimating emission releases,
• authored various emission inventory reports, and
• established the first provincial GIS system for emission inventories.

Tony holds Bachelor and Master Degrees in Engineering and is a Registered Professional Engineer.

2. "A Report on Air Quality in the CRD (1983-1997)"

Warren McCormick

Air Emissions Engineer

B.C. Ministry of Environment, Lands and Parks

Nanaimo, B.C.

This report reviews air quality data within the CRD. The data has been obtained primarily from two long term air quality monitoring sites described here as the Victoria Air Quality site (located at 1250 Quadra Street from 1983 to 1997) and the Saturna Island site (from 1992 to 1997). However, this report also considers some short term studies that have been carried out in the CRD during recent years.

For the most part the air quality within the CRD, and specifically the city of Victoria, is considered to be good. Meteorology, lack of restrictive topography, and few industrial operations are some of the major components that work to keep air quality good.

Sulphur dioxide, carbon monoxide, suspended particulate matter (PM₁₀) and precipitation acidity levels have all shown improvements over the study period. Ozone and nitrogen oxides have either remained about the same or have shown a slight increase during this period. Fine particulate matter (PM_2.5) levels have improved over the study period but maximum values are occasionally above the proposed Level B objectives.

Reductions in ambient levels of sulphur dioxide, carbon monoxide, suspended particulate matter and precipitation acidity are considered to be due to reduced oil usage since the introduction of natural gas to Vancouver Island, reduction/relocation of industries from downtown Victoria, and improvements to automotive engines.

Dissatisfaction with single strategy approaches, the inability to adapt national policies to individual airsheds and their unique characteristics, and recent thinking about environmental management utilizing watershed and ecosystem management approaches have led to a reconsideration and experimentation with more varied and comprehensive air quality strategies. These approaches include targeting both point and non-point sources of pollution, with a range of strategies including land use planning and community education.

The process has been an education one for the members of the Prince George Air Quality Management Committee. The aim of the multi-agency committee was to develop an air quality management plan that would ensure present and future air quality issues would be taken into account by stakeholders and those groups with a vested interest in the Prince George airshed.

For the city of prince George, implementation of the recommendations from the Prince George Air Quality Management Plan ahs been a step by step process that has and continues to involve City Council, City Administration, Departments, and staff and the general public. Lessons learned from this municipality will help other cites, who are initiating an air quality management plan or are drafting bylaws that are aimed to improve the air quality of a local airshed, to look at the many angles involved in such a dynamic process.

The AirCare Vehicle Emission Inspection and Maintenance Program has been in operation in the Lower Fraser Valley of British Columbia since 1992. During this time, over 8 million inspections have been performed on approximately 1.6 million vehicles. The program has been forthright in publishing statistics relevant to its operation and has developed an evaluation methodology for quantifying the emission reductions attributable to the program. Cumulative benefits for the first 8 years of program operation are estimated to represent a 30% reduction in the light-duty vehicle emission inventory from the 1992 baseline. Fleet turnover has been estimated to account for a reduction of a similar magnitude, meaning that vehicle-generated emissions have decreased by more than 50% since 1992. According to the experience of program administrators, key factors for operating a successful inspection and maintenance program include the following:

• a rigorous inspection procedure and stringent standards to correctly identify high-emitting vehicles;
• an effective training and monitoring program for the repair industry to ensure that most high-emitters are restored to normal performance; and
• monitoring and reporting on key program performance indicators on a continuous basis and making adjustments as needed.

The paper will identify areas where emission reductions can be lost such as waivers, program avoidance, ineffective repairs, and test-to-test variability and will identify potential solutions either implemented or considered to mitigate these effects.

Around April 17, 1998, there was detected throughout much of the Northwest US an extreme aerosol event that was widely attributed to an influx of Asian-sourced dust, known as 'Kosa'. Radiometric observations in Pullman, WA and atmospheric particulate sampling in Spokane, WA were used to study this event. Aerosol Optical Thickness t 500 nm attained a maximum of > 0.4 as compared to background values of ~0.2, at 500 nm, corresponding to PM₁₀ mass concentrations of ~ 80 ug/m³. Elemental analysis of samples from Spokane for aerosol events over several years permitted testing of the hypothesis that the April '98 event was predominantly Kosa, and significantly different from other more common regional and local types of aerosol events.

Joseph Vaughan became involved in modeling as a contractor working on the ROM and RADM projects from 1985 through 1991, where he also participated in early discussions on Models-3. In 1991 he took a job at the Institute of Atmospheric Physics at University of Arizona, working with Prof. Robert Dickinson in global climate modeling.

The worldwide concern over adverse health effects from fine particles has sparked an interest in instrumentation that can provide continuous information on particulate matter (PM) fine mass concentration and certain key chemical components contained therein (e.g., particulate nitrate, sulfate, organic carbon, elemental carbon, metals, etc.). Regulatory agencies and research programs both have a common need for high time resolution targeted PM fine mass data that can be used for public awareness, health research and regulatory planning.

Rupprecht & Patashnick Company (R&P) has introduced a suite of new monitoring tools to provide direct measurement of PM-2.5, particulate nitrate, particulate sulfate and particulate carbon. The Series 1400a TEOM® PM-2.5 Monitor measures near real-time PM mass concentration using a new sharp-cut cyclone inlet, optional sample equilibration system, and "AB" technology for enhanced short-term measurement stability. The Series 5400 Ambient Carbon Particulate Monitor provides the measurement of organic and elemental carbon using an automatic thermal-CO2 method. The Series 8400N Ambient Particulate Nitrate Monitor determines the mass concentration of particulate nitrate contained in PM-2.5 every ten minutes using the flash vaporization technique developed by Aerosol Dynamics. Its sister instrument, the Series 8400S Ambient Particulate Sulfate Monitor, provides particulate sulfate data. A brief overview of the theory of operation and physical configuration for each monitor is discussed. Field data and applications will be presented.

All available particulate matter (PM) data to the end of 1999 in British Columbia were analyzed for spatial patterns and temporal variation on various time scales. We found that PM₁₀ and PM_2.5 concentrations are highest in the interior of the province and lowest in coastal areas. The relatively short monitoring history at most sites precludes a robust trend analysis, however, PM₁₀ levels appear to be decreasing at a number of sites in the province. Analysis of monthly PM₁₀ data shows two predominant patterns. In the Lower Fraser Valley, the highest concentrations are observed during late summer while the lowest are found between November and March. At interior sites, the highest concentrations are typically observed in the late winter/early spring and the lowest in December/January. Data from PM_2.5 sites consistently indicate that the highest concentrations occur during the fall. The Lower Fraser Valley sites also experience higher concentrations of PM_2.5 during the summer months. Lowest concentrations typically occur during winter. Mean mid-week PM₁₀ concentrations are 30% higher than those on Sundays, when the lowest concentrations are typically observed. Weekday to weekend differences in excess of 50% are observed at sites in the central interior suggesting industrial/commercial activities as significant sources of PM₁₀. Relatively little day-to-day variations were observed for PM_2.5 suggesting the predominant role of transportation and residential heating as sources of PM_2.5.

Greenhouse gas (GHG) management has become both a national and an international priority. In December of 1997, 160 nations, including Canada, agreed to establish binding limits for greenhouse gas emissions through Kyoto Protocol. Greenhouse gas management has also become an important issue for the British Columbia government, and the Greater Vancouver Regional District (GVRD) and its member municipalities. Delivery of regional services by the GVRD requires the operation and maintenance of infrastructure which consume significant energy resources and involve disposal of large quantities of municipal waste.

This study presents the 1997 GVRD corporate greenhouse gas inventory for the three predominant GHGs (carbon dioxide, methane and nitrous oxide) originating primarily from the management of regional solid and liquid wastes. Additionally, emission estimates from the 1997 inventory have been used to prepare an emission inventory backcast to 1990 and a forecast to 2010. Total GHG emissions from the GVRD corporate operations, in 1997, were approximately 333,000 tonnes of CO2 equivalent, which was comprised of approximately 73% CO2, 26% CH4 and less than 1% N2O. Disposal of regional solid waste accounted for the major portion (84%) of total 1997 GHG emissions. The results of the backcast to 1990 indicate that total GHG emissions from the GVRD corporate emissions remained unchanged between 1990 and 1997. The forecast results, however, indicate that total GHG emissions originating from the GVRD corporate operations may rise to approximately 424,000 tonnes of CO2 equivalent by the year 2010.

A management plan for GVRD corporate GHG emissions is being prepared. Emission reduction measures that have been implemented and/or are being evaluated include employee trip reduction program, purchase of alternate fuel vehicles, energy efficiency improvements, utilization of landfill gas, and power generation at the incinerator.

Greenhouse gas emissions (GHG) originating from municipal solid waste (MSW) disposal sites account for approximately 3% of total greenhouse gas emissions in Canada. At the municipal (corporate) level, these emissions could be as high as 80-90% of total GHG emissions. After signing the Kyoto Protocol in December 1997, Climate Change issue has become a national priority in Canada, and many local governments participating in the Partners for Climate Protection program are now in the process of preparing and implementing local climate action plans. Management of greenhouse gas emissions originating from municipal solid waste has been the main focus of such activities.

The objectives of this study are to identify emission reduction options, and where possible, to assess their greenhouse gas reduction potentials for various municipal solid waste management practices.

Source reduction practices, such as reduce, recycle and re-use, have proven to be effective in reducing the greenhouse gas emissions, both at the landfills and the industrial facilities that are involved in the supply and production of relevant material. However, no matter how effective those practices are, a significant portion of organic material that is responsible for methane generation is still disposed of at landfills. In this study, the greenhouse gas emission reduction potential of dry and wet landfills was investigated for various gas collection efficiencies. Also, the GHG impacts of a number of energy utilization options, including electric power and steam generation, were assessed both for landfills and incineration. Lifecycle GHG analyses were also conducted for both aerobic and anaerobic landfill options. Study results indicate that effective energy utilization options at MSW disposal sites offer a tremendous greenhouse gas reduction and/or offset potential.

CO₂ emissions are intrinsic to the process of cement-making and cannot be reduced by the traditional methods of energy conservation or fuel-switching. The solutions must take a more innovative approach based on pollution prevention principles.

CANMET, a division of Natural Resources Canada has developed a concrete mix, commonly refereed to as high volume flyash concrete (HVFC), using roughly 60 percent flyash and 40 percent cement. Flyash is a by-product of coal-fired power plants. Canada and the US produce a huge quantity of flyash annually with the majority going to landfill.

The Greater Vancouver Regional District (GVRD) has commenced an initiative to adopt and actively promote HVFC as a positive step toward reducing CO₂ emissions as well as other associated air contaminants. The Liu Centre for Global Studies at the University of British Columbia was the first project to use HVFC in the province and reports its use has resulted in 1/3 less CO₂ emissions. This initiative was applauded by Environment Minister, The Honorable David Anderson, as "the kind of innovative planning and action that is going to make a difference".

The federal government’s Technology Early Action Measures (TEAM) Climate Change Action Fund (CCAF) is supporting GVRD’s efforts. This TEAM project involves the demonstration of HVFC in several concrete structures and a communications/outreach program on the deployment of this technology. The main objective of this project is to remove obstacles and barriers that prevent full utilization of this technology in order to realize early action greenhouse gas (GHG) emission reductions both locally and nationally.

A clean energy revolution is breaking out. Solar energy, the world's second fastest growing energy source, is positioned to reach mass scale in coming years. Wind power, at number one, is posting growth rates in the same stratosphere as internet and cell phone companies. Fuel cells, moving to commercialization faster than expected, will be widespread in cars and buildings by the end of the decade.

This clean energy revolution is coming just in time. It holds the opportunity to rapidly phase out fossil fuels, by far the major source of human greenhouse gas emissions that are already warming the climate. The recent spate of record hot years has spurred the heads of the top climate monitoring organizations in the United States and Britain to break with any past scientific reticence and clearly state that human activities are warming the globe.

Patrick Mazza is a staff writer/researcher with Climate Solutions, an Olympia Washington-based group working toward making the Northwest a Leader in global warming solutions. Mr. Mazza has been writing on sustainability issues for over twenty years.

Heat pumps are refrigeration machines that take heat from one place and deliver it to another at a higher temperature. The kitchen refrigerator is the most ubiquitous example of a heat pump; air-conditioning, water coolers, pop machines, freezers and all the cooling devices that contribute to our high standard of living are other examples of heat pumps. What happens to the heat that is removed from the refrigerator, freezer, etc.? Typically, it is discharged into the atmosphere surrounding the appliance, but sometimes, in commercial applications, it is discharged into water.

The heat pump as we know it is simply a refrigeration machine that is connected into a system in such a way that the heat discharged by the refrigeration machine is deliberately put to use for heating purposes, rather than being considered a waste product to be disposed of. The heat output consists of the energy put into the refrigerant vapor by the compressor plus the energy extracted from the heat source.

The two types of heat pumps commonly in use today for space and domestic water heating are the air source and "geothermal" source heat pumps. Geothermal includes surface water, well water or the earth itself.

The output of a standard heat pump is highly dependent on the temperature of a heat source. As the source gets colder, the heat output declines. Geothermal heat sources are invariably warmer than the air during the coldest weather. The Pacific Ocean never freezes, large lakes never freeze to the bottom, and the frost line even up by the BC-Yukon border only goes down about 7 feet. Thus, in freezing weather, a geothermal heat pump has more heat available to it than an air source heat pump has and therefore can deliver more. If the backup coil can be eliminated, the homeowner and the utility both benefit. Add the environmental benefits and it's a win-win-win situation.

As an exercise, Vancouver Island and the adjacent Gulf Islands will be used as a theoretical case study for geothermal heat pumps. This area has a growing population and therefore a steady load growth. The Island has six hydro-electric plants which last fiscal year produced 2.03 megawatt-hours of electricity. Single family and duplex residential accounts consumed just over 3 million MWh. electric energy to provide the 1 million MWh shortfall, all the multi-family housing usage (which is significant), all commercial and industrial usage had to be imported from the Mainland, that is, from the Interior of the province. Some of the undersea cables are deteriorating and an eventual failure is inevitable. If something isn't done, the Island faces an energy imposed negative growth rate in a few years.

Can geothermal heating in all houses currently heated with electric resistance heating offset the need for the new 250 megawatt gas fired thermal plant being planned for the Island, and if so, how much CO2 would not be produced?

George Pinch received his Bachelor of Engineering degree (Mechanical) from the University of Saskatchewan in 1958. After transfers to Winnipeg, Regina and back to Vancouver, and a couple of job changes, he was able to switch from sales to a position that involved more engineering when he joined BC Hydro in 1979. Since that time, Mr. Pinch has been involved in energy conservation, although the name of the conservation group has metamorphosed from conservation to Power Smart. In the 1980's, he became a builder trainer in the R2000 energy efficient housing program. His experiences with this program led him to concentrate on residential energy issues, from construction and building codes to heating systems and indoor air quality.

Mr. Pinch has served on committees formed to convince the writers of the BC Building Code that minimum insulation levels for houses should be stipulated in the Code; on the committee that developed the British Columbia module in the Model National Energy Code for Housing, and assisted the City of Vancouver with the drafting of the residential component of the City's Energy Utilization Bylaw.

Mr. Pinch is a Life Member of ASHRAE (American Society of Heating, Refrigerating and Air Conditioning Engineers) and a Past President of the BC Chapter. He is Chairman of the Greater Vancouver Home Builders Association Technical and Education Committee and recipient (twice) of the GVHBA Technical Excellence award. He is also a member of the Heating, Ventilating and Cooling Industry Association of BC and of the Residential Hot Water Heating Assoc. of BC.

Hydrogen (H2) is a clean, renewable energy form. It can be converted to electricity with high efficiency either by direct combustion or through its use in fuel cells. Solid wastes are bio-chemically heterogeneous substrates that are, in nature, slowly metabolized by a complex community of microorganisms, which convert the organic matter, ultimately, to carbon dioxide (CO2) and methane (CH4), which are green house gases that contribute to global warming. Alternatively, organic matter can be gasified thermally to produce a fairly homogeneous mixture of gases comprised, primarily, of carbon monoxide (CO) and hydrogen (H2), which can be used as a carbon source by certain species of anaerobic bacteria. The CO-oxidation pathway of these bacteria results in the synthesis of H2 that can be captured and used in fuel cells to generate electricity. Biotechnology offers tremendous potential for technological innovations that can address both waste management and energy issues.

Dr. David B. Levin is an Associate Professor in the Department of Biology at the University of Victoria (UVic).
