The road gritting salt was already on the site and was covered by secured, waterproof sheeting. The council's planning committee had raised concerns that the information supplied did not adequately demonstrate that there would be no adverse effects on the watercourses and groundwater of the surrounding area or that any impacts could be sufficiently mitigated. But the inspector disagreed, considering the risk assessment submitted considered the in-depth geology and hydrogeology of the site, as well as the proposed mitigation and environmental impacts of the salt stockpile. The inspector noted the findings of the report identified that the downward percolation of contaminants from the stockpile was significantly limited by the existing clay soil and therefore in terms of contamination of groundwaters, subject to the recommended mitigation measures, the residual risk would be very low in terms of magnitude and would also be low for surface waters. The inspector also noted that the statutory consultees were satisfied that any issues could be satisfactorily addressed by conditions. On this basis, the inspector concluded it had been sufficiently demonstrated that the retention of the salt stockpile would not result in harm to the surrounding watercourses and groundwater in terms of contamination from pollutants.
