3 BACKGROUND Skretting operates a facility in Bayside that produces approximately 40,000 MT per year of fish feed destined for the aquaculture industry. The raw materials, consisting of fish meal, poultry meal, feather meal, soybean, corn gluten meal, whole wheat, and other nutrients are blended, pelletized, dried, coated, and stored for shipping. In general, the plant consists of a storage area for raw materials and finished products, conveying and mixing equipment, a hammermill, an extruder, enclosed bins, several cyclones, a dryer, a Bio filter odour removal system, and associated screening, bagging, and air pollution control equipment. As required under the Air Quality Regulation -- Clean Air Act, the facility operated by Skretting is considered a source and therefore must apply for and obtain an Air Quality Approval to Operate from the Department. The facility is required to conduct its operations according to conditions outlined in the issued Air Quality Approval aimed at preventing unfavorable air quality conditions. The conditions are generally wide-ranging and may include such requirements as: limitations on operational parameters; requirements for testing and monitoring emissions from specific unit operations; requirements for testing and monitoring the ambient air quality surrounding the facility; requirements to operate air pollution control equipment; limits on emissions that are approved to be released to the atmosphere; provisions for equipment upgrade and/or maintenance; requirements for environmental emergency and/or compliance reporting; and other conditions aimed at minimizing the facility's impact on the environment. The Regulation provides for approvals to be issued by the Minister of the Environment for a specified period, not to exceed five years. The current Approval to Operate the Skretting facility in St. Andrews, New Brunswick (identified as I-7886) issued under the Air Quality Regulation expires on July 15, This document is intended to provide: background information on the Skretting facility, a list of potential air quality impacts associated with the facility, and a review of the facility's compliance with its current Air Quality Approval to Operate. PROCESS DESCRIPTION RAW MATERIAL STORAGE AND HANDLING Raw materials such as fish meal, feather meal, soy bean, and whole wheat, are ground in a 15-tonne-per-hour hammer mill and mixed in a 20-tonne-per-hour batch mixer. 3

4 EXTRUSION & DRYING The product is then conveyed to an 8-tonne-per-hour Jesma-Matador extruder which forms it into pellets, and on to a 12-tonne-per-hour Wenger Manufacturing dryer. The dryer includes seven stages of drying, operating at an overall temperature of 100 C. PRODUCTION & PACKAGING Once the pellets are dried, they are screened in a 20-tonne-per-hour screener. Additives are added in a 700-litre, 15-tonne-per-hour fish oil addition system. The finished product is conveyed to a bagger for packaging. ODOUR CONTROL The current bio-filter system was implemented in The biofiltration system uses a wood medium to remove odours. The bio-filtration system uses a wet scrubber to remove solid particles from the air stream and cool the air to 40 degrees Celsius or less. The air stream is then directed through the wood medium and filtered for seconds prior to being discharged to the atmosphere. The water used in the wet scrubber will be reused in the extrusion process. The wood medium needs to be replaced after 5-8 years of use. HEAT ENERGY SYSTEM Heat and steam are provided to various parts of the process by a Hurst boiler rated at 186 kilowatts, burning approximately 185 MMBTU CNG. The boiler exhausts through a 0.4-metre diameter stack 6.1 metres above ground level. POTENTIAL AIR QUALITY IMPACTS There exist potential environmental impacts to the atmosphere from the operation of the facility. The following list of potential air quality impacts have been identified and are the focus of present and future Air Quality compliance: odours from the processing of fish meal; emissions of particulate matter from the process and fugitive sources; and exhaust gasses from the boiler. AIR QUALITY COMPLIANCE AND ENFORCEMENT Skretting is required to comply with the Air Quality Regulation - Clean Air Act and operate under terms and conditions established in its Approval to Operate, issued pursuant to Section 3 of the Air Quality Regulation - Clean Air Act. Conditions are aimed at ensuring that the facility's environmental impact during its day-to-day operations does not adversely affect air quality in surrounding areas, as well as regionally and globally. Any violation of the conditions of the Approval may be subject 4

5 to compliance and enforcement measures as described in the Department of the Environment and Local Government's Compliance and Enforcement Policy. Current Air Quality Approval to Operate Terms and Conditions and Compliance History: The main Terms and Conditions that the facility is required to comply with as per the current Air Quality Approval to Operate I-7886 (issued on July 16, 2012, and expiring July 15, 2017) and the company's associated compliance history to date are summarized below: Skretting must operate its Heat Energy System so as not to exceed 10 tonnes of SO 2 and 3 tonnes of NOx per calendar year. Year Skretting Reported Skretting SO 2 NOx Cap 10 tonnes 3 tonnes Reported The Approval Holder has been in full compliance with this requirement of the Approval during the period of the Approval. Skretting must not exceed 1 tonne of PM from all sources per calendar year. Year Skretting Reported PM Cap 1 tonne The Approval Holder has been in full compliance with this requirement of the Approval during the period of the Approval. 5

6 Skretting must operate its Odour Control System at all times when the Facility is in operation. The Approval Holder has been in full compliance with this requirement of the Approval during the period of the Approval. Skretting must ensure odour emissions from the Facility do not adversely impact off site receptors. If they do, they must develop, submit and implement an Odour Prevention and Control Plan. The Facility has not had any odour complaints over the life of this Approval. Skretting must ensure fugitive particulate emissions from the Facility do not adversely impact off site receptors. If they do, they must develop, submit and implement a Fugitive Particulate Matter Prevention and Control Plan. The Approval Holder has not received any complaints regarding fugitive particulate emissions from the Facility during the period of the Approval. Skretting must ensure noise from the Facility does not adversely impact off site receptors. If they do, they must develop, submit and implement and Noise Prevention and Control Plan. The Approval Holder has not received any complaints regarding noise from the Facility during the period of the Approval. Prior to October 31, 2013, the Facility shall undertake an Odour Emission Study. Since the odour control system was implemented in 2012, the odour emission study was deferred to By February 15 of every year, the Approval Holder shall submit to the Director, with a copy to the Saint John Regional Office of the Department, an Annual Environmental Report for the previous calendar year. As a minimum, the report shall include: i) a summary report on the monthly Inspection and Performance Evaluation Program conducted on the Odour Control System; ii) a summary report on the monthly Fuel Oil Inventory which includes the amount and type of fuel used at the facility along with the sulphur percent by weight for each type of fuel used; iii) a summary report on the monthly Wastewater Inventory which includes the volume of the wastewater generated at the Facility and directed to the Champlain Industrial Park Wastewater Treatment Plant; 6
