Covering slurry lagoons under IPPC. Part 1 - Scoping study - AM0117

Covering large lagoons of slurry may be a useful technique for reducing ammonia emissions that could be implemented under IPPC. Covering an existing large lagoon may create safety hazards and may be very expensive on some farms. A short study is proposed, which is mixture of desktop work and farm visits, to assess the range of sizes that could be retrospectively covered under IPPC. This, together with an analysis of the effects of rainfall on the volumes of rainwater and slurry to be managed, will be used to prepare a shortlist of possible sites at which and experimental and demonstration programme could be located. The costs of covering two lagoons, in areas with contrasting rainfall, will be established and a proposal for an experimental and demonstration programme on these sites will be submitted to DEFRA. This follow-up programme will be designed to assess the practicability of covering large lagoons and to enable the approach to be demonstrated to key representatives of the pig industry, DEFRA, the Environment Agency and agricultural contractors.
1 To assess a number of slurry lagoons for their suitability as experimental and demonstration sites.
2 To select a shortlist from these and estimate the impact of covering on rainwater and slurry management.
3 To highlight factors at the sites that either limit or enable covering under IPPC.
4 To select two contrasting sites from the shortlist where a subsequent experimental and demonstration covering programme may take place.
5 To estimate the costs of covering a lagoon at both of these sites and prepare a CSG7 for an experimental and demonstration programme.
