User Group (England) 10th October 2007
2
The Past … Defra, the Audit Commission & DCLG agreed to use WDF for BVPIs from 2006/7 onwards in March 2006. User Group consulted on calculation methodology in April 2006 Revised questions (18, 69) in WDF for 2006/7 reporting in September 2006 Detailed guidance released onto WDF website in August 2006 Letter from Defra & CLG in September 2006 New BVPI reports on WDF in October 2006

The present … National data set downloaded for 2006/7 by Defra in early August 2007 and sent to AC for EDC. District Audit conducted during August/September/October Any data issues to be directed to AC via Webform by 8th October To be reviewed on case by case basis by AC and Defra during October -> finalised dataset for release in November

The future …? Calculation
Want to continue for 2007/8. Important that any issues are sorted out during the year, not after WDF data submission/validation has ended! Definitions Gully waste? Other? Calculation 82a-d<>100%? Your feedback is essential to make this work!

Overview of calculation method
84: total hh waste = collected for recycling (10, 12, 16, 17, 18hh, 33, 34), excl. rubble & reuse, plus residual from households in Q23. For WDAs includes WCAs recycling, and Q14 WDA recycling. Also forms denominator for 82. 82a,b; tonnages sent for recycling/composting (net of rejects) from Q10, 12, 16, 17, 18 (hh only), 33, 34, excludes rubble & reuse. Minus MRF rejects (% due to hh). Minus Q19 rejects (% due to hh).

Overview of calculation method…
82c; [inputs to Q54 and Q57 plus RDF produced in Q56 plus diverted for energy recovery from other routes (59, 64, 65) minus diverted for recycling from Q57]* %hh waste for energy recovery (Q69 or Q23 ratio) plus recycling rejects to energy recovery. 82d; [inputs to landfill, 51, 52, 53, plus diverted for landfill from other routes (56, 59, 60, 64, 65)]*%hh waste for landfill (69) plus recycling rejects to landfill.

Overview of calculation method…
84a – total hh waste/population from Q1, (to be updated) 86; net total collection cost Q31. No. hh in Q2. 87; net total disposal cost Q32. Total MSW=all Q23 plus all recycling tonnages (including WCAs for WDAs) 91a; at least one recyclable – total of Q7 91b; at least two recyclables – from Q7 (sum of 2, 3, 4+).
