Environment Agency Audit Form for Stack emissions monitoring

Audit forms and check sheets for stack emissions monitoring

It is strongly recommended that regular audits of MCERTS accredited stack emissions monitoring organisations are carried out to ensure the accredited organisations continue to meet the requirements of MCERTS.

We strongly recommend that where possible audits are carried out on an unannounced basis. This gives the truest reflection of how work is normally carried out.

The audit forms are in Word format, so they can be adapted by the auditor. To help the auditor, notes in italics have been added to the forms.

The forms are:

A1: Operator, auditor, monitoring organisation and MCERTS documentation

A2: Health and safety

A3: Isokinetic sampling, wet chemistry and multiphase sampling

A4: Instrumental methods

Check sheets have also been included for checking site specific protocols and monitoring reports.

If you have any comments on the audit forms or check sheets please contact Rupert Standring at rupert.standring@environment-.uk

|A1: Operator, auditor, monitoring organisation and MCERTS documentation |

|Operator | |

|Release point(s) | Unique stack identification from Permit. |

|Auditor(s) |  |

|Monitoring organisation |  |

|Accreditation |Check that monitoring organisation has MCERTS accreditation for the sampling method and relevant |

| |supplementary parameters, such as oxygen. |

|Team leader |At least one member of the team must have MCERTS Level 2 plus the Technical Endorsements relevant to the|

| |methods required. |

| |TE 1 particulates; TE 2 multi phase (e.g. dioxins); TE 3 gases by manual methods; TE 4 gases by |

| |instrumental methods. |

|Team member |Must be a Level 1, 2 or registered as a trainee. |

|Site review |Date it was carried out. Was it done by a site visit? |

|Site specific protocol (SSP) |Does it meet MCERTS requirements? (see template in MCERTS performance standard). Does it match the |

| |permit? (e.g. methods listed, reference conditions). |

|Deviations from SSP |Are there any requirements in the SSP that the test team believe they will not be able to follow? If so,|

| |ask them to explain and justify deviations. |

|Methods manual |Check the monitoring organisation’s methods manual is available on site. |

|A2: Health and safety |

|Permit to work | |

|Risk assessment |Must be signed off by each team member on each day. |

|COSHH assessment |Should be available for chemicals brought to site by monitoring organisation and for chemicals in the |

| |stack gas. |

|PPE requirements |Have the monitoring team followed the site rules? |

| |Safety spectacles required while leak checking glassware and handling chemicals (e.g. solvents and |

| |solutions). |

| |Appropriate chemically resistant gloves for handling chemicals. |

| |Appropriate gloves for handling equipment and climbing ladders. |

|First aid kit |Check that an in date eye-wash solution is available. |

|Platform details |Have the monitoring team checked if there is a permanent platform inspection certificate available |

| |before going up a platform? |

| |Have the monitoring team checked that temporary scaffold has been inspected and approved? (i.e. Scaftag |

| |system). For most monitoring work scaffold should be heavy duty and fixed to a permanent structure. |

| |See TGN M1 for further information. |

|Emergency rescue plan |Have the monitoring team checked if there is an emergency rescue plan in place? |

|Work area |Is it tidy? Check for trip hazards from trailing leads. |

|Exclusion zone |Work area below a platform must be clearly cordoned off. |

| |Men working overhead signs in place. |

|Lifting system |Observe how the equipment is lifted to the working area? |

| |Is it done manually? Is a portable lifting system used? Is it secured to a suitable structure? Is the |

| |equipment showing signs of wear and tear? |

| |Have personnel been on lifting and slinging courses? |

|Port sealing / gas venting |Check how the sampling access port is sealed during sampling? If working in an enclosed area, is the |

| |sample gas vented safely? |

|Communications |The team may need to communicate when working in different areas (i.e. ground level and platform). How |

| |do they communicate? Telephone, radio, shouting. Are man down alarms used? |

| |Has communication been established with staff responsible for operating the process? (e.g. control |

| |room). |

|Working hours & rest periods |Is the work plan sensible? |

| |Has it taken driving to and from site into account? |

| |Is artificial lighting available for work when it’s dark? |

|Chemical storage |Do the monitoring team have fridges, solvent cabinets and cool boxes? |

| |Are items clearly labelled? |

| |Check use by dates on solutions and solvents. |

|Cylinder storage |Are all the cylinders secured? (i.e. tied up or held in racks). |

| |Check cylinders are not transported with regulators on. |

| |Check regulator inspection dates. Check that regulators are in good condition. |

|Electrical equipment |Does it look in good condition? Is it all PAT Tested? If using 240 V, are there RCDs in place? |

|A3: Isokinetic sampling, wet chemistry and multiphase sampling |

|Pre-sampling |

|Type of test |e.g. Particulates. |

|Standard number |e.g. CEN, ISO etc. |

|Pitot leak check |Both Pitot openings should be checked for leaks before use. |

|Stack temperatures and pressures |These must be recorded on stack traverse sheet. |

|Angle of gas flow |Is a swirl test carried out? |

| |How is the angle of gas flow measured? |

| |The angle of gas flow should be less then 15° at each sample point. |

|Moisture |How was the pre-test moisture for pre-sample calculations obtained? Was it measured, estimated or based |

| |on historical data? |

|In-stack / out-stack |Out of stack testing is required if there are water droplets. |

|Sample duration |WIs, LCPs and BS EN 14181 specify minimum sample durations. |

| |If a batch process, how has the sample regime been decided? (e.g. peak emissions). |

|LOD |Check LOD is ................
