Sediment. Extraneous matter or sediment in milk includes cow hair, dirt, manure, dust, vegetable matter and insects. Bacteria accompanies sediment into the milk, resulting in contamination. The presence of sediment in milk can affect the taste, appearance and quality of manufactured products. The two samples the driver takes daily will be used to do a random test for each fifteen-day period. This will generate a PASS/FAIL result. If the result is FAIL, then the supplier will be tested every pick-up until the situation is rectified. More than three FAIL tests will give the supplier a downgrade in quality.
Sediment. Owner will make accommodation for the removal and disposal of all the accumulated pollutants and sediments. Temporary storage will be provided onsite in a reserved area(s). The sediment will need to be disposed of in an appropriate manner within two weeks after being removed from the storm drain system.
Sediment. Addressing ecotoxicological impacts on sediment-dwelling organisms (benthic biota) requires the incorporation of an additional compartment into the existing framework. Based on the evaluation of maturity, quality, and availability of existing approaches for addressing sediment in multimedia fate modeling, a sediment compartment is a potentially important addition to the proposed framework, particularly in light of persistent substances with a potential to build up high exposure concentrations in sediments and related organisms. In addition, for certain chemicals such as cyclic siloxanes, sediments provide potential transfer pathways for bioaccumulation (Xxxx et al. 2013). Required data for including ecotoxicity to sediment- dwelling organisms are becoming more readily available and could be sufficient to become part of LCIA. If sediment toxicity effects could be estimated by ecotoxicity data for pelagic species (e.g., via equilibrium partitioning for nonpolar organic chemicals), such an inclusion would put a stronger emphasis on sediment-binding chemicals of concern, as just mentioned. Because aquatic sediment belongs to aquatic ecosystems, we suggest considering effects on benthic and sediment species for integration into 2 overall aquatic ecotoxicity impact scores (i.e., freshwater and marine).
Sediment. Driveways, parking areas, and rooftops are expected to be common sources of sediment due to wear.
Sediment. Extraneous matter or sediment in milk includes cow hair, dirt, manure, dust, vegetable matter and insects. Bacteria accompany sediment into the milk, resulting in contamination. The presence of sediment in milk can affect the taste, appearance and quality of manufactured products. The two samples the driver takes daily will be used to do a random test for each fifteen-day period. This will give us a PASS/FAIL result. If the result is FAIL, then the supplier will be tested every pick-up until the situation is rectified. More than three FAIL tests will give the supplier a downgrade in quality. The freezing point test is used to detect any added water. Adverse freezing point values may either indicate the presence of extraneous water or occasionally poor nutritional status of the cow or herd. In most cases a freezing point under -0.517, will indicate the presence of extraneous water, over and above that of the natural water content of milk. BPD may test for both freezing point at times throughout the year to ensure customer requirements are met. When picking up milk from a supplier, tanker drivers have been instructed to complete a sensory test on the milk. The tanker driver will check that the supplier’s milk meets the following criteria: • White to cream in colour • Free from foreign matter, taints and coagulation • That it has no abnormal odours. This test is at the discretion of the tanker driver and they are given the authority by BPD to reject any loads of milk that do not meet the criteria above. The supplier’s Field Services Officer will be informed and will come out and check that the supplier’s milk is fit to be collected. If so, then the tanker driver will return and pick up the milk. The supplier will be penalised at the company’s discretion for any loads that fail the sensory test. Graph 1.
Sediment. If the failure scenario depicts the effects of sediment release, note “Includes reservoir sediment release”.
Sediment. In conjunction with instream effectiveness monitoring and trends monitoring, PALCO will monitor data on instream sediment levels, channel morphology, stream bed aggradation/degradation, and biological metrics sensitive to sediment (e.g., invertebrate diversity). PALCO will assess the effectiveness of the sediment control measures by monitoring sediment production rates from roads and hillslopes. In this way, PALCO will detect any shortcomings in sediment control measures earlier than if the company depended only on instream conditions. PALCO will institute alternate management approaches to address identified shortcomings through the adaptive management process. PALCO will conduct sediment source inventories as part of the watershed analysis process for each hydrologic unit. These studies will provide baseline data on the number, location, and size of sediment sources on the ownership. In addition, these studies will provide sediment budgets identifying the amount of sediment being delivered to waters from different sources. Within five years of completing the baseline sediment studies, PALCO will conduct followup studies. These will determine the extent to which these sediment sources remain active and new sources develop (e.g., how many slides have occurred in the interim), their relationship to management activities, and how the rates of management-related surface erosion and landslides compare to the rates in the baseline period. PALCO will continue to inventory surface erosion within harvest units, bank erosion, new landslides, and road-related failures as they occur. These followup studies will continue to be completed at five-year intervals in conjunction with the watershed analysis revisitations for the life of the PALCO Aquatics Conservation Plan. Hillslope and instream effectiveness monitoring and trends monitoring will provide the necessary information for determining how the PALCO Aquatics Conservation Plan affects sediment delivery to waters. In addition, because the followup studies will examine the relationship between management and sediment production, PALCO will use study results as guidance on how to modify management activities, if necessary, to reduce sediment production through the adaptive management process. Sediment parameters are perhaps the most difficult on which to conduct effectiveness monitoring. Given this difficulty, PALCO will modify its approach for determining the effectiveness of sediment control measures as new data an...
Sediment. Selenium already contained in sediments in the Drain is a source of concern because flows may suspend and transport sediments; selenium may migrate into the water column; and sediments may act as a sink, and selenium may concentrate into sediment. Under normal operations, flows will be slow enough to not cause sediment movement. Monitoring activities will detect any movements or selenium migration. In the event that selenium in sediments migrates into the water column, such selenium will be measured as part of the monitoring program which will, among other things, measure selenium levels in Mud Slough downstream of the Drain (Site D). Sediments will be removed well before composite concentrations indicate hazardous material values.
Sediment. Solid fragments of inorganic or organic material that come from the weathering and erosion of rock and are carried and deposited by wind, water, or ice.
Sediment. The contractor shall remove and dispose of sediment when accumulations reach approximately one-half the fence height, or sooner when directed by the engineer. If required by heavy sediment loading, a second silt fence shall be installed as directed by the engineer.
