Being the Technically Competent Manager (TCM) on a hazardous waste transfer station is not a badge you hang on the office wall. It is a set of regular, hands-on visits where I check that what happens in the yard matches what the environmental permit says should happen.
One of the sites I cover is a waste transfer facility on Ferry Lane South in Rainham, east London. It handles hazardous liquids, waste oils and mixed industrial wastes, right next to the river. Here is what the role looks like in practice, and why it matters.
What a TCM actually is
Every permitted waste site in England must show it is run by competent people. The permit here says it plainly: the operator shall comply with the requirements of an approved competence scheme (condition 1.1.4). In practice that means a named TCM holding the right WAMITAB or equivalent qualification, attending site often enough to genuinely oversee it.
The TCM is not the site manager and does not run the day-to-day operation. The role is closer to an independent technical conscience: someone who understands the permit conditions, walks the site, spots drift before it becomes a breach, and records it. If the Environment Agency asks who is technically responsible, the answer has to be a real person who has been there recently and can prove it.
What a TCM visit looks like
Each visit follows the permit, not a generic checklist. I walk the site, talk to the team on shift, look at the paperwork and write it all up in a TCM site visit report the operator can show the regulator.
Waste acceptance. Are loads checked against the permitted codes and the producer's paperwork before they come off the vehicle (condition 2.3.2)?
Storage quantities. Is the site within the 72.5 t and 336 t caps on the day, and are hazardous wastes kept apart unless mixing is authorised (condition 2.5.8)?
Containment. Do containers holding liquids have secondary containment that is intact and not full of rainwater (condition 3.2.3)?
Oil and effluent treatment. Is the separation plant and carbon polishing working, and is the discharge to sewer point S1 being monitored as required?
Records and returns. Are quarterly waste returns, monitoring records and the annual performance report up to date and kept on site?
Management system. Is the written management system current, are staff trained, and have complaints, incidents and near misses been logged and acted on?
Housekeeping. Odour, noise, pests, spills and general site condition, especially given the river boundary.
The report records what was seen, what needs fixing, who owns it and by when. The next visit starts by checking those actions were closed.
What tends to catch sites out
Most problems on a site like this are not dramatic. They are small slips that build up between inspections.
Creeping storage. A busy week, a delayed collection, and suddenly the yard is over its tonnage cap without anyone noticing.
Bund neglect. Bunds that collect rainwater or debris lose capacity, so they will not hold a spill when it matters.
Paperwork lag. Waste returns filed late, monitoring records incomplete, or the management system still describing how the site worked five years ago.
Mixing creep. Compatible-looking wastes combined for convenience when the permit does not allow it.
Overdue reviews. The permit asks for four-yearly reviews of energy use, raw materials and the waste hierarchy. These are easy to forget because nothing breaks when you skip them.
A good TCM visit catches these early, while they are still an action on a report rather than a finding in an Environment Agency compliance assessment.
Why it matters
For the operator, a reliable TCM is evidence of competence the regulator can see. It protects the permit, supports a better compliance score and keeps the site ready for an unannounced inspection. For everyone around a riverside site in Rainham, it is one more set of trained eyes making sure hazardous waste stays where it should.
