Environmental guidance for your business in Northern Ireland & Scotland
Your fabricated metal product business may use galvanising baths to coat your metal products with a layer of zinc.
Zinc reacts with the metal, usually steel, in the galvanising bath to form a series of iron-zinc alloy layers. This produces a thick coating that makes your metal resistant to corrosion, impact and abrasion.
If you have a permit, licence or registered exemption you must comply with its conditions. Your permit may contain conditions which control the quantity and concentration of your air emissions.
You may need to reduce your emissions to meet the limits in your permit. You can be fined or even sent to prison if you do not comply with conditions.
Your galvanising operations could produce a number of different waste materials, including:
You must comply with your duty of care responsibilities when you deal with your waste.
Do not discharge anything to public sewers, surface waters or ground waters without consulting your regulator. You may need a discharge consent or other authorisation. For further information, see our guidance on discharges to water and sewer.

My Year at NetRegs, A reflection on my time as an intern with the NetRegs team at SEPA. An overview of all the activities and projects I had the opportunity to participate in during my Bright Green Environmental Placement.
A day with Hydrology, SEPA's hydrometry unit is responsible for around 400 gauging stations and 350 rainfall monitoring sites. River gauging stations are important as they allow river levels to be monitored so flood events can be predicted and flood warnings sent out.
