Managing the environmental impacts of AMWS operations — spill risk, discharge control, waste duty of care, carbon and nuisance. The full aspects and impacts analysis is held in APP_06; this assessment covers the operational risk arising from those aspects.
This assessment is numbered in the home and office series but its subject is operational environmental management. Its classification is flagged for the September 2026 Management Review to decide where it properly belongs.
AMWS operational sites, the yard, both units and the fleet.
| Hazard | Existing controls | Initial | Additional controls | Residual | ||||
|---|---|---|---|---|---|---|---|---|
| S | L | R | S | L | R | |||
| Diesel or hydraulic oil spill at the yard or on site | Spill kits held at the yard and carried in vehicles, checked weekly by site teams (APP_18); SOP 9.3 Land & Water; COSHH_24 Diesel; toolbox talk TBT-2026-03 on diesel and hydraulic spills delivered March 2026 | 3 | 3 | 9 | Spill response refresher on the rolling programme in February 2027; environmental emergency drill with documented scenarios (CAR-2026-008, Sean Ashton and Jason May, target 30/09/2026) | 2 | 2 | 4 |
| Chlorinated water discharged to a watercourse or surface drain during disinfection | MS 3.6 Disinfection method statement; SOP 9.3; COSHH_07 Chlorine Tablets; toolbox talk TBT-2026-04 on chlorine discharge control delivered April 2026; dechlorination before discharge | 4 | 2 | 8 | The environmental emergency drill (CAR-2026-008) to include a chlorine discharge scenario, since this is the most likely EPR-notifiable event on AMWS work | 3 | 1 | 3 |
| Waste not segregated, or duty of care not evidenced | Licensed carriers only; waste transfer notes retained; SOP 9.4 Waste Management and SOP 9.5 Hazardous Waste; Waste Carrier registration valid to 12/08/2028; KPI E2 targets over 80% diversion from landfill | 3 | 2 | 6 | Waste transfer note completeness checked as a recorded item at the monthly Onyx site visit; the recycling initiatives note kept current as supporting evidence | 2 | 1 | 2 |
| Carbon footprint not reduced against the published baseline | 2025 baseline published 12/05/2026 at 288.7 tCO2e Scope 1 + 2, with diesel accounting for 97%; annual reporting at the Management Review under KPI E3; fleet transition to Euro 6 with two vehicles outstanding (APP_10 L31, target 01/12/2026) | 3 | 3 | 9 | No reduction target has been set yet — targets to follow once practical levers are identified (Sean Ashton, target 31/12/2026, carried forward from the May 2026 Management Review). Until a target exists this is measurement without commitment, so the residual stays medium | 3 | 2 | 6 |
| Energy and water waste at the premises | LED lighting fitted throughout both units; last person out switches off lighting and equipment; premises energy is a minor part of the footprint next to diesel, which is 97% of Scope 1 + 2 | 2 | 2 | 4 | None — effort is better directed at the 97% of the footprint that is diesel | 2 | 2 | 4 |
| Dust or noise affecting neighbouring units or residents | Working hours observed; SOP 9.6 Environment in the Office covers the premises; Control of Pollution Act 1974 duties recognised in APP_10 L28 | 2 | 2 | 4 | None — no complaints received and the yard activity is light | 2 | 2 | 4 |
| Disturbance of protected species or habitat during site works | Wildlife and Countryside Act 1981 duties recognised in APP_10 L29; SOP 9.2 Wildlife & Plants; ecological constraints checked at job planning and flagged in the RAMS | 3 | 2 | 6 | None beyond SOP 9.2 — the constraint is identified by the client's design and confirmed at planning | 2 | 2 | 4 |
This document is maintained under AMWS's continuous-compliance model. Substantive revisions are reviewed and signed off by the Directors at the standing weekly Director / HSQE compliance call (Sean Ashton, Onyx + Leanne Mason). Currency, cross-references and minor edits are checked at the monthly Onyx site visit. The annual Management Review (September) provides the strategic-level confirmation. Compliance is therefore continuous, not gated on a single annual meeting.
