Can an operation use production sites that have had sewage sludge applied in previous years OR use sewage sludge during the season?

No. Sewage sludge either used in previous years on production sites or used during production is NOT acceptable. An operation that uses production sites where sewage sludge has been applied in previous years will lose points in Section C Question #2 of the audit checklist. Operations that apply sewage sludge during the season will autofail in Section E Question #1 of the audit checklist.
