PCME - Passionate about Particulate

25 Years of Innovation


PCME provides a full range of instruments to satisfy requirements derived from legislation affecting industrial plant including:


                                   European Directives and Legislation

Requirements of national industrial environmental regulations across European States are similar and are converging as a result of EU Directives which must be transposed into National Law within defined timescales.

The three core EU Directives affecting industrial processes are:

The proposed Industrial Emissions Directive would consolidate these distinct requirements in a single piece of European legislation.

Emission Limits and monitoring requirements are defined directly in the Directives or derived from the framework defined in the industry specific BREF (Best Available Technique Reference) documents and country specific interpretation of BREF notes (e.g. sector notes in UK) which are written to support the IPPC directive.

WID QAL1 approved CEM as part of EN-14181 (to monitor with defined uncertainty) MCERTS approved
LCPD QAL1 approved CEM as part of EN-14181 (to monitor with defined uncertainty) MCERTS approved
IPPC Monitoring plan to support minimisation and control of emissions Application appropriate type of monitoring specified in Industry Sector Note
• Filter dust monitor
• Filter leak monitor
MCERTS approvals are not mandatory but are strongly recommended in support of OMA

Air Quality Directive
The Air Quality Directive defines upper limits on the concentration of several pollutants including Total Suspended Particulate Matter, PM-10, and PM 2.5 in the ambient air. In locations with high ambient levels, industrial emission limits and monitoring strategy may well be customised to support overall air quality objectives.

                                   UK Legislation and Requirements

Pollution Prevention and Control (PPC) is the UK legislative implementation of the IPPC, LCPD and WID Directives and covers approximately 2000 industrial processes in the UK. The large and more complex industrial sites (Part A1 sites) are regulated by the Environment Agency (EA) while Local Authorities regulate other plant falling under the IPPC directive (Part A2 plant) and the 10,000 plus industrial plant falling under Part B Air Pollution control regulations.

Part A Sector notes (published by the Environment Agency for each of 40 plus industrial processes) provide guidance on Best Available Technique (BAT) for the specific industry. Emission limits and monitoring requirements are covered in the Sector Notes. Requirements for Particulate Measurement systems and Leak monitors are covered in these requirements.

Part B Guidance Notes (published by the Local Authority Unit) provide guidance on BAT for 60 types of industrial processes regulated by local authorities. These are updated every 4 – 6 years to reflect changes in the interpretation of BAT and new technology and cover emission limits and monitoring requirements. Requirements are for particulate measurement systems and indicative monitoring of arrestment plant performance (leak monitoring).

OMA: Operator Monitoring and Assessment (OMA) is a scheme resulting in a 3 yearly audit conducted on Part A processes to assess the quality and adequacy of monitoring on the site. This scheme encourages good monitoring practice including the use of CEMS approved by MCERTS, appropriate CEM maintenance and data management.

Method Implementation Documents (MIDs) are documents published by the Environment Agency to clarify interpretation of European Standards when applied to the UK. MIDs have international significance due to their robust and pragmatic approach to regulation and standards implementation.

                                                      US Legislation

New Source Performance Standards (NSPS) are published for each major type of industrial processes covered by the Clean Air Act 1990. These define stack monitoring requirements including the use of Continuous Opacity Monitors (usually compliant to PS-1). Some revised NSPS standards (eg Power, Refinery) allow the use of PM-CEMS (PS-11 compliant) as an alternative to Opacity. In wet FGD stacks with saturated flue gas and incinerator stacks with very low levels of emissions, it is not possible to use Opacity and, therefore, PM-CEM monitoring is required.

Maximum Control Technique (MACT) rules apply to processes with Hazardous air pollutants (HAPS). These rules include requirements for monitoring including the use of PM detectors and Bag leak detectors (see Steel, Aluminium, Portland Cement, Boiler MACT).
