• Air Quality Management Plan

  Levelton Engineering developed a comprehensive basis for an air quality management plan for the Greater Vancouver region of British Columbia, Canada. The plan remains the first of its kind in Canada. The regional government has approved, and is proceeding with implementation of the air quality management plan for the region.

  Levelton Engineering provides engineering and planning services to assist government and industry with the development of measures to improve urban air quality. These include assessment of local air quality and monitoring programs, preparation of emission inventories and emission growth forecasts, analyses of the benefits from possible emission control strategies, and preparation of air quality management plans.

  Staff are specialists in the preparation of emission inventories and the control of emissions of common and toxic pollutants from mobile, industrial and commercial sources. Past studies of emissions and control strategies have included motor vehicles, power plants, refineries and chemical plants, evaporative solvent loss, gasoline marketing, consumer products, marine vessels, aircraft and most other sources present in urban areas. With regard to motor vehicles, analyses have considered vehicle fleet characteristics, traffic data, future tailpipe standards, the effectiveness of vehicle inspection and maintenance programs, gasoline reformulation and gasoline vapour controls. Forecast of future emission with and without implementation of additional controls has been done using estimates of growth in source activity levels, and technological data on the types and performance of possible emission controls.

  Levelton Engineering sells and maintains computer software to store and report emission inventories for mobile, point and commercial sources. The user-friendly software simplifies initial inventory preparation and inventory updates, stores activity levels, emission factors, growth factors, emission control assumptions and other critical information, and generates estimates of present and future emission levels for the control strategies of interest. If desired, Levelton Engineering will train local client personnel in emission inventory techniques which best suit local issues and sources of information, and in the use and maintenance of the computerized inventory.

• Composting Technology

  Due to the high cost associated with remediating petroleum contaminated soils using conventional techniques (especially if transport is required), Levelton Engineering offers composting technology as an effective, low-cost alternative treatment. The process uses only natural raw materials and the indigenous bacteriological population to remediate the soil in treatment cells at the site. The advantage of this process is four-fold:

  Cost-effective: typical costs are $15-$25/m3 of contaminated soil; environmentally beneficial: composting uses only natural raw materials and the end product can be used for landscaping, backfill, as a soil conditioner etc. Fast: reduced hydrocarbon concentrations to non-regulatory levels in 11 weeks Low-tech, Low Cost: Electric blowers and continuous turning of soils with heavy equipment typically required for conventional techniques are not needed.

• Discharge Of Treated Effluent On Forest Or Grass Land.

  Industrial or municipal effluent of suitable quality can be disposed of onto forest or grass land with benefits to plant growth and groundwater availabilty and no adverse environmental effects, provided there is appropriate control of effluent parameters and the application rate. This approach is well suited to cases where alternate means of effluent disposal are not available, or where water needed for irrigation is in short supply.

  Levelton Engineering assesses and designs spray irrigation systems for discharge of treated industrial or municipal effluent onto forest and grass land in situations where an environmentally acceptable alternative means of discharge is not available. Levelton Engineering's scope of services includes field investigation of soil, groundwater and vegetation to assess the suitability of the soil, terrain and vegetation for spray irrigation, design of the spray irrigation system and irrigation program, specification of a suitable monitoring program to ensure the system is not adversely affecting soil, vegetation or groundwater, and assessment of potential environmental impacts.

• Performance Tuning

  Emissions of NOx from coal or oil fired boilers can be reduced by performance tuning alone or in conjunction with modifications to alter or stage combustion conditions in the furnace. These techniques have been applied successfully and cost effectively to utility and large industrial boilers.

  To reduce NOx emissions from boilers using combustion modification techniques, Levelton Engineering first undertakes a testing program to characterize current combustion conditions, emission rates, combustion air flows at each level in the furnace and the effectiveness of boiler controls. Based on these results Levelton Engineering develops recommendations on changes to the boiler that are needed to reduce NOx emissions while achieving the desired energy output levels. These are discussed and refined through consultation with plant staff. Plans are expanded as appropriate to solve other operating deficiencies and constraints on boiler output and performance.

  Levelton Engineering works with the plant owner to implement and verify the effectiveness of the combustion modifications and any changes made to boiler instrument control strategies. The scope of work can include engineering design, performance testing, project management and procurement of equipment. These improvements can be followed up with training of operating staff to take full advantage of the modifications and to ensure the NOx reductions are maintained. The improvements achieved by boiler performance tuning include reductions in emissions of criteria contaminants and improvements in boiler efficiency, resulting in associated reductions in emissions of greenhouse gases.

  Levelton Engineering staff have provided the described solution to improve boiler performance and reduce NOx emissions for clients across the United States.

• Prediction Of Pollutant Dispersion And Acidic Deposition.

  The prediction of pollutant dispersion and acidic deposition of industrial emissions in mountainous and rolling terrain is achieved using (1) a automated meteorological monitoring tower and a Sound Detection and Ranging (SODAR) unit for upper air data if not available from nearby stations; (2) remote data acquisition and quality control; and, (3) dispersion modelling using CALPUFF, RTDM, ISC/2 and ADEPT/2, as appropriate.

  Levelton Engineering designs, commissions and operates cost-effective meteorological monitoring stations for collection of meteorological data needed to assess the impact of industrial emissions on air quality. System operation and performance is monitored and data is down-loaded remotely via a telephone link. Quality control and quality assurance programs have been developed for field audits of the monitoring station, as well as verification of the acquired meteorological data. Unique expertise has been developed for operation of these stations for long periods, through harsh winter weather conditions and in mountainous terrain. The tower provides data for winds at 10-30 m, while the SODAR provides data for winds at 50-500 m.

  Meteorological data collected by the station is processed, then used along with calculated source emission rates to predict ground-level concentrations and acidic deposition rates. The CALPUFF and the ISC/2 models are used for complex and non-complex terrain, respectively. Predictions of wet and dry sulphate deposition rates are made using the ADEPT/2 model. Custom programs prepare the meteorological data for input to the dispersion models and report key system performance and meteorological values. Ground- level pollutant concentrations and acidic deposition rates predicted by the models are used to assess the potential for adverse environmental impacts. Based on these results, Levelton Engineering can develop appropriate air quality and biomonitoring programs.
