Water Quality and Drainage (Chapter 11)
WQD1	Loch Lomond, Watercourses 1 – 3 & Drainage Paths 1 - 4	The Contractor shall produce a Site Management Plan (SMP), which will describe the specific procedures to be put in place to control sediment mobilisation, surface water discharges, and spillages. The SMP shall be discussed and agreed with SEPA prior to commencement of site works, and all staff on site shall be briefed on and trained in the procedures contained within the SMP. The SMP shall incorporate best practice guidance as detailed in PPG’s published by SEPA and CIRIA Reports C532 & C648, as a minimum. In particular, the following measures shall be adopted on site: - CAR Licences shall be obtained prior to start on site (note this is a separate consenting regime from the approval of the planning application) for work in the loch and the Watercourses, and these shall be displayed prominently on a notice board in the site offices, Identify and clearly sign all surface water features during site set up and brief personnel on their location during induction, Site compound and site access routes shall be clearly defined during site set up with the minimum number of watercourse crossing points clearly defined. Formal watercourse crossings shall consist of a piped culvert and vehicle access over the top, The Contractor shall provide bunds around all fuel, oil, and other chemical stores, and shall centralise and minimise the number of these stores, A formal wheel wash and concrete wash out area shall be set up on site and this shall drain to a lined sump with the surface water either treated on site or disposed of to a licensed facility off site, Overburden shall be stripped in sections and shall be the minimum area required for that phase of the works, Stripped areas and stockpiles shall have silt fences placed so as to intercept the surface water run off from these areas, The Contractor shall give consideration to creating the sustainable drainage system infrastructure at the outset of construction work, and this could then be used to treat some of the construction stage site run off prior to discharge. If this is not done the Contractor shall provide some other form of treatment to the surface water run off from the site prior to it reaching the watercourses, Construction materials and other stockpiles shall be stored away from the surface water features (minimum 10m), Plant shall be stored and maintained away from surface water features, The Contractor shall instigate re-vegetation of stripped areas on a sectional basis as early as possible within the programme to reduce the potential for silt laden run off, Measures to minimise sediment disturbance, increased turbidity, and spread of spillages during works in the Loch shall be implemented to prevent a plume of sediment or other pollutant extending out into the loch. This may involve floating booms and a silt fence around the working area, Watercourse realignments and culvert extensions shall be undertaken prior to road widening	Site Management Plan & obtain CAR licence	Prior to & During Construction	The SMP shall identify a clear monitoring regime to confirm the application of the above mitigation requirements. It is anticipated that the Contractor’s site management personnel would be made responsible for monitoring and in practice many of the measures could be monitored based on a daily or weekly inspection of the site and the completion of a "mitigation requirements" tick sheet. These tick sheets would then be retained as auditable evidence of the monitoring of the mitigation requirements.	SEPA
WQD2	Surrounding land	The Contractor shall ensure that all culverts are inspected on a daily basis and shall keep all culverts clear of construction / non-construction debris for the entire duration of the construction period, The Contractor shall keep close control of permanent and temporary earthworks operations in the vicinity of Watercourses 1, 2, & 3 and Drainage Paths 1 – 4 to prevent any obstructions of the Watercourse / Drainage Path channels, The Contractor shall not store materials within or immediately adjacent to watercourse / drainage path channels, Where works in the watercourse / drainage path channels are required (i.e. for culvert extension / replacement), the Contractor will be required to provide temporary flow bypass facilities (e.g. temporary damming of the watercourses / drainage paths just upstream and the provision of pumps on a duty and stand by arrangement) with sufficient capacity to pass a 1:20yr flow or other such temporary requirement agreed with SEPA in the CAR Licensing process, All engineering works within the watercourses and drainage paths will need to be carried out in accordance with the Controlled Activities Regulations (i.e. a CAR Licence will be required), The timescale of such operations would need to be limited to prevent significant effects on the passage of flows (i.e. works to be undertaken during low flow periods only), All work within watercourses or drainage paths shall be undertaken in accordance with a detailed construction method statement to be produced by the Contractor and discussed and agreed with SEPA in advance of the works	Construction Method Statements & CAR licence	Prior to & During Construction	The Contractor’s site management personnel will ultimately be responsible for monitoring the application of most of these mitigation requirements. Again it is suggested that the monitoring of the application of mitigation requirements is completed via regular inspections of the site and the completion of a tick sheet which summarises the mitigation measures in a readily useable for rapid assessment on site.	SEPA
WQD3	Loch Lomond, Small Watercourses & Drainage Paths	Geomorphology Working areas on the loch shore and within the loch, and around and within the Watercourses & Drainage Paths shall be clearly set out prior to commencement of construction works, and these shall be the minimum areas required to safely complete the works, The Contractor shall not store materials within or immediately adjacent to watercourse / drainage path channels, Plant movements should be kept to a minimum on the loch shore and on the banks of the Watercourses / Drainage Paths, A survey to record the form and vegetation along the loch shore and the watercourse / drainage path channels shall be completed by an ecologist or a water engineering specialist covering the area predicted to be disturbed during the works. This information shall provide sufficient detail to allow the alignment, levels, and form of the shore and channels to be reinstated after the works, Reinstatement shall include re-vegetation with local plant species to stabilise the structure of the completed shore / banks, As noted above, all engineering works within the watercourses and drainage paths will need to be carried out in accordance with the Controlled Activities Regulations (i.e. a CAR Licence will be required) Hydrology As noted above, the Contractor shall ensure that all culverts are inspected on a daily basis and shall keep all culverts clear of debris, As noted above, construction materials and other stockpiles shall be stored away from the surface water features (minimum 10m), As noted above, consideration shall be given to creating the sustainable drainage system infrastructure at the outset of construction work, as this could then be used to attenuate some of the construction stage site run off prior to discharge. If this is not done the Contractor shall provide an alternate means of controlling the surface water run off from the site to ensure the culvert capacities are not exceeded, The Contractor shall apply for a temporary discharge licence under the Controlled Activity Regulations if required by SEPA for the works.	Site Management Plan Construction Method Statements Temporary Site Drainage Design Pre Works Survey CAR Licence Reinstatement of Watercourses	Prior to & During Construction	Monitoring of the mitigation measures would be achieved via the Client’s Agent inspecting the site during set up to supervise the working areas being set up and ensure they are the minimum practical working areas, and also inspecting the site during the works to confirm the working areas, material storage areas, and reinstatement works are being undertaken satisfactorily.	SEPA
WQD4	Groundwater	None required at this stage	None	N/A	None	-
WQD5	Groundwater	As noted above, the Contractor shall produce a Site Management Plan (SMP), which will describe the specific procedures to be put in place to control site discharges and the potential for pollutant spillages. The SMP shall be discussed and agreed with SEPA prior to commencement of site works, and all staff on site shall be briefed on and trained in the procedures contained within the SMP. The SMP shall incorporate best practice guidance as detailed in PPG’s published by SEPA and CIRIA Reports C532 & C648, as a minimum. In particular, the following measures shall be adopted on site in relation to mitigating the potential effects on groundwater quality: - The Contractor shall provide bunds around all fuel, oil, and other chemical stores, and shall centralise and minimise the number of these stores, The Contractor shall complete all servicing, fuelling, and storage of vehicles at construction compounds, The Contractor shall provide dedicated wash down areas for concrete and other delivery vehicles, The Contractor shall implement drainage control measures at the site to prevent areas of standing surface water that could become contaminated and leach into the shallow groundwater. Where collection of water at the site is unavoidable (e.g. within excavations), provision should be made for this water to be collected and passed through some form of treatment before discharge), The Contractor shall liaise with SEPA regarding any proposed discharge from the site in respect to the Controlled Activities Regulations.	Site Management Plan	During Construction	As noted above, these are to be monitored by the Contractor’s site personnel and the Client’s Agent based on regular inspections using a tick sheet assessment.	SEPA
WQD6	Loch Lomond, Watercourses 1-3 & Drainage Path 4	The new sections of road incorporate SUDS principles as far as practical, by providing a mixture of filter drains and a dry swale for the treatment of the road run off. These measures have been agreed with SEPA (refer to email dated 04/08/10 in Appendix B). In addition, it is noted that the proposed road alignment and profile has been designed to improve safety and hence reduce the risk of serious accidents and spillages from such accidents in the first place.	Drainage Design	Design Stage and During Operation	Design Review & During regular maintenance	SEPA
WQD7	Loch Lomond, Watercourses 1-3 & Drainage Path 4	Works to road infrastructure shall be completed under an approved method statement (approved by route manager within maintenance authority) and shall incorporate best practice measures (including the SEPA Pollution Prevention Guidelines, General Binding Rules, and CIRIA Reports C532 & C632) to reduce the risk of significant of major sediment disturbance and spillages of potential contaminants to the surrounding water resources features.	Method Statement	During Operation	Provisions for monitoring the application of the best practice measures would also need to be noted in the method statement, and in practice this will likely mean that the supervisor of the works will be responsible for ensuring the application of the best practice measures on site.	-
WQD8	Surrounding land from development	The realigned channels and extended / replaced culverts shall be designed in accordance with the guidance in CIRIA Report C689 in regard to hydraulic capacity. This would generally be the acceptance of a 1:200yr flow. However, given the rural nature of the area upstream of A82 at this location SEPA may accept design to a lower return period. The designers of the scheme shall confirm the design return period with SEPA for all the culverts. The storm flows shall be calculated for the watercourses / drainage features where works are proposed using FEH or similar accepted hydrological assessment methods. The designers shall ensure that the rates of release of the surface water run off from the surface water drainage system are in accordance with the guidance provided in CIRIA Report C697 for acceptable rates of run off and advice from SEPA and the Local Authority regarding acceptable Greenfield run off rates.	Drainage Design	During Design	Design Review	SEPA
WQD9	Loch Lomond, Small Watercourses & Drainage Paths	The design of the extended culverts shall ensure that, as a minimum, the existing hydraulic capacity is maintained, but also refer to flood risk mitigation requirements noted above. The design of all new or extended culverts shall be undertaken with due consideration to the guidance contained in "River Crossing and Migratory Fish: Design Guidance", and where fish passage is considered possible then the new or extended culverts shall be designed in accordance with the above guidance. The channel realignment proposals shall include the replication of the form and vegetation of the natural channels. Where bank protection works are considered necessary these shall be "green" bank protection works (refer to "The Water Environment (Controlled Activities) (Scotland) Regulations 2005 - A Practical Guide" for details). Any bank protection works on the watercourses upstream and downstream of the realigned A82 shall be kept to the minimum length required, and shall not extend beyond the extent of the channel realignments (i.e. anticipated to be a maximum of around 60m across the three watercourses). The advice within CIRIA Report C551 Manual on Scour at Bridges and other Hydraulic Structures shall be taken into account in the design of the culverts.	Drainage Design & General scheme Design	During Design	Design Review	SEPA
WQD10	Watercourses 2 & 3 and Drainage Path 4	The surface water drainage proposals for the scheme include an element of SUDS design (including filter drains and a dry swale) fitted within the physical constraints of the site (refer to Figure 11.2 for further details). These features will provide some level of attenuation of the run off before discharge to the proposed northern and southern outfalls. It is understood that Argyll & Bute Council have confirmed that no specific surface water drainage attenuation is required for the development, presumably based on the fact that the loch is immediately downstream of the discharge points. However, it is always preferable to adopt best practice where possible, and it is therefore recommended that the designers try (physical restrictions permitting) to ensure that the rates of release of the surface water run off from the road drainage system is in accordance with the guidance provided in CIRIA Report C697 for allowable rates of run off and that the combined flows (watercourse flows and surface water run off flows) do not exceed the capacity of the culverts.	Drainage Design	During Design	Design Review	SEPA
WQD11	Watercourses 2 & 3 and Drainage Path 4	None required at this stage.	None	N/A	None	SEPA
WQD12	Groundwater	None required at this stage.	None	N/A	None	SEPA
WQD13	Groundwater	The surface water drainage proposals for the scheme include an element of SUDS design (including filter drains and a dry swale), and the use of linear filter drains wherever possible assists in reducing the risk to groundwater (refer to DMRB Method C). It is therefore considered that these proposals be adopted as mitigation requirements to assist in reducing the potential effect on the groundwater.	Drainage Design	During Design	Design Review	SEPA
