There is a farmer spreading slurry, causing dreadful distress to neighbours due to smell/there is a factory nearby and the smell is dreadful at times. Can the EPA do anything about this?
There are procedures and guidelines dealing with slurry spreading (there may be local by-laws).
If farmers follow these procedures then the problems of odour are considerably reduced but they won't be eliminated.
Local problems such as these should be dealt with locally, e.g. by the Local Authority.
If the industry causing the odour problem is licensed by the EPA then we should be contacted.
All licences issued by the EPA contain provisions relating to odour.
