Point Source Pollution

June Graham, Policy Development Officer, SEPA

Polluting Discharges

Unlike the other regulatory regimes the point source regime will not be entirely new as it will replace/subsume controls currently in place under Part II of the Control of Pollution Act 1974 (CoPA) and the Groundwater Regulations (1998). At present, discharges of trade and sewage effluent to controlled waters require consent. Other discharges, such as uncontaminated surface water, are exempt, unless specifically prohibited by SEPA.

Proposed Transition Arrangements

1.1 Existing Licensed Activities

It is anticipated that the majority of dischargers with COPA consents and Groundwater authorisations would have to apply to transfer their consents/authorisations to a WEWS licence. Any controlled activities that are not covered by a licence would have to apply for a WEWSA authorisation. Current proposals are that all licences would have to be transferred between the period April 2005 and September 2005.

It is proposed that the existing conditions and limits would apply without modification unless current operational practice was not compliant. Provided there was no unacceptable environmental impact the WEWS licence would reflect current practice. Otherwise, pre-existing conditions would be retained.

Transferred authorisations not complying with their existing conditions would have to be reviewed as soon as possible to identify any investment required by 2012. Time-limited licences authorising continued operation might be needed for the interim period. .

1.2 Other Existing Controlled Activities

SEPA will work with dischargers to progressively review those transferred authorisations where mitigation measures would be required to deliver WFD requirements. The reviews would not constrain existing discharge performance but will provide dischargers with the advanced warning of requirements for December 2012.

1.3 Priority Substances

The WFD requires the cessation or phasing-out of discharges, losses and emissions of Priority Hazardous Substances within 20 years of the Commission submitting proposals for the control of priority substances. It is anticipated that a Priority Substances Daughter Directive will be adopted in 2004. This means that Priority Hazardous Substances will not be permitted in any authorised discharge from 2024, irrespective of the legislative regime, i.e. IPC authorisation, PPC permit, Waste Management licence or WES authorisation.

D ischarges, losses and emissions of less hazardous Priority Substances have to be progressively reduced which means that all water-use activities currently contributing an environmental load of a Priority Substance will be required to investigate and incorporate means of minimising its presence in waste streams.

Regulatory Controls

The point source regime will have the generic hierarchy of authorisation; licence for high risk discharges/activities, GBR for medium risk and Registration for low risk.

Of particular challenge in developing the new regime is identifying;

i.  low-risk activities where standard industry practice predominates and which therefore can be adequately and effectively regulated by means of a GBR; and low-risk activities where standard industry practice predominates and which therefore can be adequately and effectively regulated by means of a GBR; and low-risk activities where standard industry practice predominates and which therefore can be adequately and effectively regulated by means of a GBR; and

ii.  low-risk activities which although currently consented under CoPA could be regulated by means of a GBR or Registration. low-risk activities which although currently consented under CoPA could be regulated by means of a GBR or Registration. low-risk activities which although currently consented under CoPA could be regulated by means of a GBR or Registration.

In order for the development of a GBR to be worthwhile the activity has to be simple, subject to common practice and sufficiently widespread to achieve efficiency savings, both to the regulator and the industry/user.

Some discharges which are being considered for authorisation by GBR or Registration are:

i.  Septic tank and soakaway systems serving small populations; Septic tank and soakaway systems serving small populations; Septic tank and soakaway systems serving small populations;

ii.  Fish hatcheries; Fish hatcheries; Fish hatcheries;

iii.  Scour valve discharges; Scour valve discharges; Scour valve discharges;

iv.  Sustainable Urban Drainage Systems. Sustainable Urban Drainage Systems. Sustainable Urban Drainage Systems.

However, where site-specific sensitivities apply an activity normally authorised by a GBR or simple Registration might require a licence, for example where there was a public health risk from a discharge liable to impact a bathing water or shellfish water.

Conversely, where water users considered that the risk from a controlled activity had diminished they could apply for review, e.g. from a licence to a GBR.

Regulatory mechanisms comparable to a GBR already exist in Scotland . The Control of Pollution (Silage, Slurry, and Agricultural Fuel Oil) ( Scotland ) Regulations 1991 define statutory standards for collection and storage and include a requirement to notify SEPA. Similarly, Part M of the Building Standards Regulations which sets out requirements for the design and construction of septic tank soakaways could be considered to be GBRs.

Issues for Discussion

The principal issues for discussion are:

1. Whether there are particular issues that need to be considered as part of the transitional arrangements from COPA consents/groundwater authorisations to WEWS authorisations Whether there are particular issues that need to be considered as part of the transitional arrangements from COPA consents/groundwater authorisations to WEWS authorisations

2. How do you think the authorisation hierarchy, specifically Registration and GBRs, may be applied to point source discharges to facilitate minimal regulatory burden? How do you think the authorisation hierarchy, specifically Registration and GBRs, may be applied to point source discharges to facilitate minimal regulatory burden?

3. Whether you consider there are specific opportunities for your respective industry/activity that would benefit from authorisation by GBR. Whether you consider there are specific opportunities for your respective industry/activity that would benefit from authorisation by GBR.

Note on legal basis

The Water Environment and Water Services ( Scotland ) Act 2003 provides for Scottish Ministers to make regulations for the control of activities liable to cause pollution of the water environment.

The Act defines -

""pollution", in relation to the water environment, means the direct or indirect introduction, as a result of human activity, of substances or heat into the water environment, or any part of it, which may give rise to any harm.

"Harm" means -

(a)harm to the health of human beings or other living organisms;

(b)harm to the quality of the water environment taken as a whole;

i. harm to the health of human beings or other living organisms;

ii. other impairment of, or interference with, the quality of aquatic ecosystems or terrestrial ecosystems directly depending on aquatic ecosystems;

(c)offence to the senses of human beings;

(d)damage to property; or

(e)impairment of, or interference with, amenities or other legitimate uses of the water environment."
