There are various requirements that follow from being a fully permitted waste site. One of these is that an employee has to be designated a Technically Competent Manager (TCM). Basically this means that they have to pass Chartered Institution of Wastes Management (CIWM) exams. To prove that they keep this knowledge current, and refreshed, the exams have to passed again every 2 years. Richard retook these exams in September and passed!
