IED Permit & BAT Assessment — Documentation

An engagement to prepare an EU Industrial Emissions Directive permit application and Best Available Techniques (BAT) assessment — documentation only, independent of equipment supply.

The Challenge

A chemical site required an Industrial Emissions Directive (2010/75/EU) permit variation, including a Best Available Techniques assessment benchmarking its water discharge against the relevant BAT-associated emission levels (BAT-AELs).

Regulatory documentation of this kind has to be technically defensible, internally consistent and aligned to the exact standard the regulator applies. A weak or incomplete submission means delay, refusal or onerous conditions. Reynolds & Bauhm was engaged purely to prepare that documentation — not to design or supply equipment.

Compliance Documentation Only

Reynolds & Bauhm was engaged on a documentation-only basis. We did not design, build or supply any treatment plant for this project — our deliverable was the complete, regulator-ready compliance package. The work comprised:

  • Review of the applicable BAT Reference (BREF) conclusions and BAT-AELs
  • Benchmarking of the site's discharge against each relevant BAT
  • Emissions inventory, mass balance and monitoring methodology
  • Drafted permit-variation application and BAT justification
  • Support through the regulator's technical queries

Documentation engagement

This was a compliance-documentation service: Reynolds & Bauhm prepared the submission and supporting evidence on behalf of the operator. Equipment design and construction were outside our scope. This is a representative example of how we deliver standalone regulatory documentation for a chemical processing site.

How the Documentation Was Prepared

We began by reviewing the site’s existing data, sampling records and process description against the governing standard, identifying gaps and commissioning additional characterisation where needed. The evidence base was then assembled into a structured submission — mass balances, emissions/discharge calculations, a best-available-techniques comparison where applicable, and a monitoring and reporting plan — written to the regulator’s template and cross-referenced to the underlying data so every figure is traceable. We supported the operator through the regulator’s queries to determination.

The outcome was a complete, defensible compliance package the operator could submit with confidence — delivered independently of any equipment supply, so the advice carried no commercial bias toward a particular technology.

Why This Approach Works

Independent & unbiased

Documentation-only engagement means the assessment is led by the regulation, not by selling equipment.

Traceable evidence

Every figure is cross-referenced to sampling data and a mass balance, so the submission withstands scrutiny.

Written to the standard

Prepared to the exact regulator template and the governing code, minimising queries and delay.

Supported to determination

We handle the regulator’s technical queries through to a granted permit or consent.
