(GP/GT) for Additional Water Supply in the Lower Rio Grande

ill-19
Certain of the technical issues which arise within the context of OP/OT brine effluent disposal are
common to disposal practice for other wastes:
(I)
Removal of entrained particulate matter and all matter not in solution.
(2) Dissolved or entrained oxygen prevention or limitation; corrosion and deposition control.
(3) pH control and tailoring, to ensure proper levels of acidity or alkalinity.
(4) Elimination or mitigation of transient conditions such as sudden changes in temperature
andlor pressure.
Other technical issues arise which are not common to disposal practice for other wastes:
(1) Temperatures higher than usual.
(2) Total flow rates and storage volumes abnormally high.
(3) Possibilities for rapid and unheralded changes in temperature and pressure when
bypassing the desalination plant (because of shutdowns), thus causing possible damage
to the re-injection well(s).
SURFACE DISPOSAL
Surface disposal may not be a viable or permittable alternative, but it must be investigated for two
reasons: subsurface disposal may not be available at a given site and the subsurface disposal permit
process requires the evaluation of at least some, if not all, alternatives. The problems posed by surface
disposal are enumerated below:
(I)
Total quantity of fluids produced daily.
(2) Salinity of fluids and protection of potable water supplies.
(3) Requirements for surge protection -
(a) Pipeline system emergency shutdown.
(b) Utilization system bypass.
(4) Noxious or poisonous gases removal or conversion.
(5) Dissolved or entrained oxygen prevention or mitigation; corrosion control.
(6) Solids removal andlor deposition control.
(1) Thermal transient prevention or mitigation. *
