Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 2094
Title: Coal Mine Wind Erosion of Exposed Land Assessment
Start date: 30 Jun 2014
 
Licence Condition
The licensee must undertake the following steps: 1.    Calculate the wind erosion exposed surface area (in hectares) within the premises as of 31 March 2015. 2.    Determine the wind erosion exposed surface area (in hectares) predicted as at 31 March 2015 within the licensee’s Environmental Assessment for the premises. 3.    Compare the areas calculated in steps 1 and 2. 4.    Submit a written report to the EPA at hunter.region@epa.nsw.gov.au containing the analysis required in steps 1 to 3, by 29 May 2015.   The report submitted to the EPA must be accompanied by spatial data to confirm the wind erosion exposed surface area calculations.  The following data is required: ·         Shapefiles showing the premises boundary. ·         Shapefiles showing the wind erosion exposed area within the premises as of 31 March 2015 ·         Shapefiles showing areas classified as stabilised surface as of 31 March 2015. ·         Details of any studies undertaken to verify that the areas of stabilised surface meet the definition.
Environmental Assessment means any environmental assessment document prepared in order to gain approval or consent under the Environmental Planning and Assessment Act (1979) under which the licensee currently operates at the premises.  If the predictions made in this document do not correspond to the current year of mine operation, the licensee should extrapolate between predictions.   Stabilised Surface means any previously disturbed surface area which shows visual or other evidence of surface crusting and is resistant to wind-driven fugitive dust and is demonstrated to be stabilised. Stabilisation can be determined in accordance with one or more of the applicable test methods contained in the Rule 403 Implementation Handbook located at: www.capcoa.org/Docs/SCAQMD%20r403%20handbook.doc.   Wind Erosion Exposed Surface Area means the portion of the premises surface which has been physically moved, uncovered, destabilised or otherwise modified from its natural state, thereby increasing the potential for fugitive particulate matter emissions, but excluding  areas which have been: ·         paved or covered by a permanent building or structure; ·         maintained with a vegetative ground cover of at least 50% of ground cover for particular areas. Vegetative ground cover can be determined in accordance with the standardised procedure for revegetation assessment contained in Atyeo C. & Thackway R. (2009) located at: http://data.daff.gov.au/data/warehouse/pe_brs90000004196/revegetationManual200906_20100410_ap14.pdf  or ·         classified as a stabilised surface.
Within one (1) month of commissioning the Power Generation Plant and/or corresponding air pollution controls, the Licensee must undertake post-commissioning air emissions monitoring. The monitoring must: (a) be undertaken by a suitably qualified and experienced person(s) to the satisfaction of the EPA; (b) be undertaken in accordance with the Approved Methods for the Sampling and Analysis of Air Pollutants in NSW; (c) be undertaken when plant/process conditions represent worst-case emissions scenarios; (d) include a minimum of three (3) rounds of air emissions monitoring, at least one (1) week apart, and during a period of no longer than three (3) months; (e) in the event that the Power Generation Plant operates concurrently with the Permanent Flares and/or any temporary flare(s) during the verification monitoring required by Condition E4.2, include at least one (1) round of air emissions monitoring during the concurrent operations; and (f) sampling at each of the landfill gas engines outlet and the flares must be performed for all pollutants specified in Column 1, using the methods listed in Column 3 of the Table below.
Within three (3) months of completing the final round of testing required under Condition E4.2, the Licensee must prepare and submit to the EPA an Air Emissions Verification Report. The Air Emissions Verification Report must, as a minimum: (a)  be prepared by a suitably qualified and experienced person(s) in consultation with the EPA; (b)  be prepared in accordance with the Approved Methods for the Sampling and Analysis of Air Pollutants in NSW; (c) include the following:   i.  evidence to demonstrate the monitoring was undertaken when plant/process operating conditions represent worst-case emissions scenarios;   ii. if undertaken in accordance with Condition E4.2(e), evidence to demonstrate the monitoring required by E4.2(e) was undertaken when the Power Generation Plant was operating concurrently with the Permanent Flares and/or any temporary flare(s);   iii.  a description of the process operating conditions at the times of sampling, including a description of the process (e.g., processing rates, activities, etc.), a process flow diagram showing all inputs and outputs, and a description of all air pollution control systems;   iv.  a detailed description of the sampling location for all discharge points demonstrating compliance with Australian Standard AS4323.1 Stationary source emissions - Selection of sampling positions. Engineering drawings or schematics, and photographs should be included to support the description;    v.  a table comparing air emission monitoring results and all relevant input data, assumptions and air quality predictions made in the Air Quality Impact Assessment (AQIA) for MP06_0139 MOD 14 (Appendix C: BINGO Gas to Electricity Project, Eastern Creek Recycling Ecology Park, V04, 15 March 2024) and the Eastern Creek Recycling Ecology Park - Landfill Gas Cogeneration Plant Modification - additional air quality impact assessment, prepared by EMM, dated 29 April 2024; and   vi.  where the comparison at E4.3 (c) (v) indicates a difference between monitoring results and the AQIA predictions, or it is identified that current mitigation measures or management practices are not consistent with best practice, provide comments of the significance of the differences to results and conclusions made in the AQIA and identify additional mitigation measures to prevent and minimise emissions as far as practicable.
1. The EPA may utilise the information contained in the Air Emissions Verification Report to include additional conditions in this Licence, including emissions limits and requirements for ongoing monitoring. 2. The assessment of additional pollutants identified during the Air Emissions monitoring may be required.
Within three (3) months of completing the Air Emission Verification Report required under Condition E4.3, the Licensee must submit to the EPA a revised and updated Air Quality and Odour Management Plan. The revised and updated Air Quality and Odour Management Plan must include measurable and auditable operating parameters, informed by the Verification Report, that will be monitored to inform the efficient operation of the Power Generation Plant.
The Licensee must notify the EPA when the Power Generation Plant is being commissioned, including the planned date of operation post-commissioning.
