HUM SIGNIFICANT ENVIRONMENTALIMPACTS AND CONTROLS2.1 AIR AND ODOUR (Continued)Emissions from the Die Casting Process are controlled by:• Dust suppressors on all the furnaces to reduce the particulates being emitted to environment• A fume scrubbing system to minimise emissions from the sand moulding process• The use of low resin sand to minimise odour from the process• Daily visual inspections and continuous particulate monitoring• Regular odour checks at the boundaryImprovements in the die casting operation have focused on establishing the root cause of the odour complaintsreceived in 2009 and 2010. During the past year HUM has received 2 substantiated odour complaints from localresidents. A full review of the physical (equipment) and management systems was carried out and the followingconcerns and actions were determined.• Low pressure die casting dust filters were found to be damaged and split, and had contaminated the carbon filters.Dust filters were replaced and the Environmental Health Officer agreed that in the short term there was no need toreplace the carbon filters as they were considered ineffective• High pressure casting - manual damper used when drossing off was found to be broken in September and theprocedure for ensuring it was used was ineffective. The damper was repaired and the importance of using itreinforced with the Associates• Odour testing was updated to establish the main odour sources• Action plan developed to define and timetabled improvements for further investigationsEmissions from the petrol storage process are controlled by:• Use of vapour recovery systems to minimise vapour loss during petrol transfer• Documented control systemsEmissions from the adhesives and sealers process are controlled by:• Monitoring of VOC use using a mass balance approach• Minimisation of waste materials• Controlled application methods• Documented control systemsDie Cast Example of Operator Permit Awareness Training8SE/D/G/15 - Nov 2011www.hondamanufacturing.co.uk
2.2 WATER MANAGEMENTDescription of environmental impactThere are two types of water discharged from HUM; storm and foul water. Foul water is discharged through the publicsewers and contains effluent from HUM’s domestic facilities and waste water from HUM’s production operation. Stormwater is discharged from the roof drainage systems and car parking areas.How is the impact measured and controlled?Foul water discharge has to meet the discharge consent limits set by Thames Water as required by the Water IndustryAct and the Trade Effluents Prescribed Processes and Substances Regulations. The Environment Agency specify dischargelimits into South Marston Brook from the on-site storm water lagoon as required under the Water Resources Act.To ensure the trade effluent achieves the discharge consents, HUM operates an on-site Waste Water Treatment (WWT)facility. Waste water from the Paint, Bumper Paint and Engine processes are sent to WWT for additional treatment ina batch process. Sampling to confirm compliance to discharge consent takes place throughout the process, to achieveoptimum treatment and guarantee discharge levels.All storm water from the site is discharged through an on-site lagoon, which is a single point of discharge for the site.The lagoon is an engineered structure with a concrete interceptor at the discharge point to the off-site brook (SouthMarston Brook) which is designed to regulate the flow of water to prevent flooding down stream and prevent anypetroleum based contamination entering the brook. The quality of the water is checked monthly to ensure compliancewith the discharge consent.Activity and improvements in 2010In 2009 a trial within wastewater treatment to reduce the use of chemicals in the water treatment process wascompleted. The results were analysed during 2010. Although all of the contamination was removed the project was notviable as the quantity of filter cake that was produced was not significantly reduced.HUM received a domestic water saving audit from Thames water during 2010. There were a number of recommendationsthat HUM has now actioned. Water usage will form a key part of HUM’s future business planning process.Storm Water LagoonSE/D/G/15 - Nov 2011www.hondamanufacturing.co.uk9
