#WWEM12 Process monitoring conference

The organisers of WWEM 2012 have announced details of the process monitoring conference that will take place at the Telford (GB) event on 7th November 2012. Entitled ‘2012 Update on Regulation and Certification’ the presentations will be of interest to any municipal or industrial organisation with a discharge consent, in addition to consultants, contractors, instrument manufacturers, regulators, academia and researchers.

A further conference will take place on the second day of WWEM 2012, the Water Wastewater & Environmental Monitoring event, addressing the quality of laboratory analysis. Both Conferences have the approval of The Chartered Institution of Water and Environmental Management and can therefore contribute to delegates’ Continuing Professional Development. However, visitors will also be able to attend up to 70 Workshops and an Exhibition featuring 120 of the world’s leading organisations in this field.

The process monitoring conference will be chaired by Hugh Lloyd, Water Monitoring Association chairman, and the opening presentation will be given by John Tipping from the (British) Environment Agency (EA) who will provide an update on the Industrial Emissions Directive (IED) and outline its regulatory effects through 2013.

The IED was published on 6th January 2011 and represents the first major change in European environmental legislation since the IPPC Directive was published in 1996. John’s presentation will highlight some of the more significant changes including the future critical role for BREFs (Best Available Techniques Reference Documents). BREFs are the main reference documents used by competent authorities in Member States when issuing operating permits for the installations that represent a significant pollution potential in Europe. There are about 50,000 of these installations in Europe.

Andrew Chappell, also from the EA, will continue the European theme by explaining the advantages of coordinating instrument certification procedures and test methods with other countries. He will also report on recent work with other European Countries to develop a CEN standard based on the current MCERTS procedures for assessment of water instruments.

As MCERTS gains a greater hold in the water sector, Bob Cooper from SIRA will review MCERTS’ progress and explain future developments. He will also outline a number of case studies demonstrating international recognition of the scheme.

The potential impact of solar radiation on ultrasonic level sensors, particularly where these form part of an MCERTS certified installation for monitoring discharge, has been a much debated subject for many years. It has long been known that air temperature changes need to be compensated for in ultrasonic level measurement, but until recently there has been no firm evidence on other effects. WRc has undertaken extensive tests on typical level sensors both under operational and simulated environments which has enabled more explicit good practice guidance for the use of such equipment and more rigorous tests for incorporation into the MCERTS product approval scheme. Andy Godley from WRc will present a brief overview of this work and provide guidance on good practice.

The EA’s Rick Gould will deliver the final presentation, outlining the development of Operator Monitoring Assessment (OMA) for water monitoring; describing how it has been applied, and explaining the changes in Version 4.

The EA developed its OMA scheme in 2000, initially applying it to Integrated Pollution Control, and then to IPPC with Version 2 of OMA in the following few years. Originally applying to the monitoring of emissions to air, OMA is a systematic assessment of the monitoring provisions at a regulated installation, and the EA typically uses it to assess both the quality of monitoring, and compliance with the operator’s permit. OMA is a part of the UK’s risk-based regulation approach, in that OMA focuses regulatory attention where it is needed most, and helps to drive improvements in both monitoring and environmental protection.

In 2009, OMA was revised, streamlined and improved in Version 3, which now includes effluent-monitoring within its scope. Then in 2010, OMA was adapted to apply to the monitoring at wastewater treatment works for the purposes of the newly introduced system of Operator Self-Monitoring, and the monitoring required by the Urban Waste Water Treatment Directive. Now, after significant field-experience with OMA for water, and following reviews and feedback, the EA has revised OMA and produced Version 4. This revision applies greater flexibility depending on the complexity of an installation and its environmental risks. The revisions have also been driven by the evolution of legislation, the need for a wider adaptability, and improvements in monitoring.
