A typical component of waste management is the storing or stockpiling of waste materials for recycling or reuse. The Environment Protection Authority (EPA) requires that this action is carried out in the correct manner to ensure the probability of damage to human health and the environment is eliminated or reduced. Storage or stockpiling will have to be taken on exclusively in appropriate circumstances for genuine and favorable purposes.

Stockpile sites are used to enable the short term storage of material or tools for construction or maintenance projects. The kinds of components which may be put away are: — Select substance and fill – like sand and rock — Topsoil, wood chips, mulch and waste vegetation — Virgin Excavated Natural Material (VENM) and spoil — Recycled asphalt pavement (RAP) – rotomilled material — Concrete or asphalt block material taken from pavements — Aggregate and Pre-coated aggregate — Cold mix asphalt — Road base — Parked machinery and vehicles — Construction materials such as Jersey Kerb and traffic signs — General materials such as timber, steel etc. Stockpile sites are generally not to be used for the storing of any waste which contains coal tar or any sort of waste which is classified as unhealthy, restricted solid, special or liquid waste as classified in the Protection of the Environment Operations Act 1997 Stockpile sound management routines Just before decision is taken to start a impermanent stockpile on site a risk assessment must be undertaken with the goal of protecting against or reducing the chance of destructive blows on human health and/or the environment. In every case, the site and substance specific conditions must be thought about when deciding on the actual demands pertaining to bunding, on-site structure and community assessment. With regards to the locality, probable off-site challenges and amount of community interest associated with an action, the proper measure of community consulting may need to be set up both at the preparing and operational periods of stockpiling activities. In such cases, stakeholders including adjacent neighborhoods and nearby citizens ought to be notified on factors including duration, possible threats and impacts and the associated minimization measures. Suitable contact info of business or project managers should also be provided to the community for open correspondence to enable inquiries or complaints to be attended to. On-site risks would be determined by factors including the: — waste type and chemical and physical qualities of the materials being stockpiled — locale and climate of the site — hydrological and hydrogeological conditions which include closeness to surface and ground waters, water quality and secure environmental values — stretch of time materials are going to be stored — projected management method of the stockpiled materials Further off-site risks have to be taken into account and rely on factors like: — closeness to and sensitivity of the enveloping atmosphere (including unpleasant effects to water, human health and amenity) — exposure due to height in metres AHD of the working floor level which the stockpile is situated upon and in accordance with the encompassing environment — enactment of proper pollution control standards — supervision of traffic within the site The following environmental protection actions should be used to ascertain and maintain stockpiles on construction sites: — The border of the stockpile need to be delineated with a bund (made out of earth/RAP etc) or other type of fencing or barrier. — Materials must be stockpiled at the least 5 metres away from foliage or native vegetation, without having it pressed up around the foundation of trees. — Stockpiled materials should not be in excess of 2m tall and should have a maximum 2:1 slope. — Erosion and sedimentation regulators needs to be constructed in between the site and any drainage lines or down-slope areas. — A diversion bund need to be placed on the uphill section of the site to redirect water round the site. — Cover stockpiles with plastic or store them damped down if airborne debris may be a problem. — Stockpiles sites have to be just right to hold all needed components without burying protective precautions just like silt fences. If you have excessive material you may need to widen your site protection actions. — Stockpile sites have to be examined repeatedly to make sure that the site sign (which plainly labels and locates the site), border bunding, sedimentation and erosion controls and boundary delineation are all in order. At the end of the construction project all non permanent stockpile sites ought to be removed from site and the site restored as essential for contract specs.
