HSE involvement in development planning around high hazard industrial sites - Public forum - Planning Advisory Service (PAS)

I am one of HM Inspectors of Health & Safety. I have recently begun a project, the object of which is to investigate ways in which the Health and Safety Executive could become involved early in development planning issues around high hazard industrial (COMAH) sites. HSE is a statutory consultee with respect to planning applications within the consultation zones of COMAH sites. At present, LPAs use HSE's PADHI+ software to determine whether HSE's response would be AA (advise against) or DAA (don't advise against), the dvelopment. If HSE was involved prior to planning applications, time & money would be saved. I think that HSE involvement at the LDF stage seems the most logical, but I would like to seek opinions from people within the system.
