                       SAN FRANCISCO BAY AREA




                         APRIL - JULY 1972






I.  INTRODUCTION




     An aerial remote sensing program, requested by Region IX, was




carried out in the San Francisco Bay Area in April and July 1972.




The general area is shown in Figure 1.  During the planning phase  of




the mission the Bay area was divided into four sections and labeled




A, B, C and D, as outlined in Figure 1.






II.  MISSION PURPOSE




     The purpose of this aerial reconnaissance program was to fulfill




the following objectives:




     a)  Provide location and description of industrial discharges




         during day and night-time periods.   This effort was designed




         to provide information for the waste source survey performed




         by NFIC-Denver.




     b)  Document the presence of and dispersion patterns for the  Bay




         area municipal sewage treatment plant (STP) discharges during




         day and night-time periods.




     c)  Document the flow patterns of Bay waters in the following




         areas:




         (1)  Carquinez Bridge near the mouth of the Carquinez Strait.




         (2)  Bay Bridge between San Francisco and Oakland.




         (3)  Golden Gate Strait.

III.  BACKGROUND INFORMATION

     The San Francisco Bay Area is the receiving water for approxi-

mately 250 discrete sources of municipal and industrial waste dis-

charges.  Approximately 150 of the waste sources are located in close

proximity to San Francisco, San Pablo, and Suisun Bays.  The total

volume of wastewater discharged by these 150 sources averaged 3.1 million

cubic meters per day [mcmd] (820 million gallons per day [mgd]) in 1971.

Municipal sources contribute nearly 58 percent [1.854 mcmd] (490 mgd)

of the total wastewater volume.

     The major sources of industrial wastes are oil refineries, petro-

chemical  and chemical manufacturing plants, pulp/paper mills, and

food processing plants.  These industries are located primarily along

the southern shore of Suisun and San Pablo Bays between the cities of

Antloch and Richmond, California.

     There are 52 municipal sources that discharge an average of more

than 0.5 mgd of wastewater each.  The three largest are:

     a)  City of San Jose - 314 thousand cubic meters per day [kcmd]
                            (83 mgd).

     b)  East Bay M.U.D. - 299 kcmd (79 mgd).

     c)  City of San Francisco - 242 kcmd (64 mgd) (North Point Plant).

     These three sources comprise approximately 28 percent of the

total wastewater volume.

     Federal installations discharge nearly 83.3 kcmd (22 mgd) of

domestic and industrial wastes into the Bay area.


IV.  PHYSICAL DESCRIPTION OF THE BAY AREA

     San Francisco Bay is a distinctive geographical feature in the

Northern California area; unusual hills, striking in appearance, lie

-------
on the outer periphery of the Bay area.  It covers approximately




1,127 square kilometers (435 square miles).  San Francisco Bay ranges




from 4.8 to 19.3 kilometers (3 to 12 miles) in width and is about




80 kilometers (50 miles) in length.




     Westernmost of the numerous large metropolitan areas in the




City of San Francisco, situated on a land mass immediately south of




the strait, Golden Gate, that is the Bay connection with the Pacific




Ocean.  The cities of Richmond, Oakland, and Berkeley are east of




San Francisco across the Bay from Golden Gate.  To the northewast are




Martinez, Vallejo, Pittsburg, and Antioch.  South of the San Francisco




area lie the cities of San Mateo, Burlingame, Redwood City, San Jose,




Hayward, San Leandro, and Palo Alto.  North of the area are Rodeo,




San Rafael, Walnut Creek, Napa, Petaluma, and Antioch.




     The periphery of the Bay is characterized by flatlands and tidal




marshland.  Approximately 80 percent of this marshland has been "re-




claimed," chiefly for agricultural use and salt ponds.  A great amount




of these lands, or shoreline, has a flat slope.  As a result, the




area between mean high and low water is relatively large which totals




166 square kilometers (64 square miles).  Another result of the effect




of this flat-slope topography is the shallow depth of the Bay.  Average




depths are about 6.1 meters (20 feet).  Immediately east of the Golden




Gate, which is only two miles wide, the average depth of the Bay in-




creases to 13.1 meters (43 feet), with a maximum depth of 40 meters




(130 feet).  The Carquinez Strait maintains a maximum depth of 27.5




meters (90 feet).

-------
V.  AIRCRAFT SENSOR CONFIGURATION/DATA




     Four high performance aircraft were used to carry out each of the




two remote sensing missions.  The sensors, carried on-board each




of these aircraft, were three cameras and an infrared line scanner




OIRLS).  The cameras on each aircraft were KS-87B Aerial Framing Cameras




equipped with 152 mm (6 inch) focal length lens assemblies.  They were




mounted in the aircraft in their respective vertical positions as




shown in Figure 2.




     The framing cameras were up loaded with different film and optical




filter combinations as follows:




     a)  Camera Station 1.  Kodak S0-397 Aerographic Ektachrome Film




         with a Wratten HF-3/HF-5 gelatin optical filter combination.




         This film is 127 mm (5 inches) wide providing a true color




         transparency measuring approximately 114 mm x 114 mm (4.5"x4.5")




         The filter combination prohibits ultra-violet light from




         reaching the film eliminating the effects of atmospheric haze.




     b)  Camera Station 2.  Kodak 2403 Tri-X Aerographic Film (127 mm




         wide) with a Wratten 47A gelatin optical filter.  This film




         filter combination provides a black-white negative having




         been exposed to near ultraviolet and deep blue optical energy.




         This sensor was primarily used for the detection of oil slicks.




     c)  Camera Station 3.  Kodak 2443 Aerochrome Infrared Film with




         a Wratten 16 gelatin optical filter.  This film is also 127 mm




         wide  (5 inches) resulting in color transparencies measuring




         approximately 114 mm x 114 mm.

-------
     The Wratten 16 filter (deep orange in color) transmits




a portion of the visible optical spectrum, i.e., deep green,




yellow, orange, red, along with the near infrared energy from




7.0 to 1.0 microns.  This film presents a modified color or




false color rendition in the processed transparency unlike




the more familiar true-color films.  It has an emulsion layer




that is sensitive to the near infrared in addition to the




red and green layers, whereas the true-color ektachrome




films have red, green, and blue sensitive layers.  (Every




color in the visible optical spectrum is formed in the true




color film by various combinations of red, green and blue




dyes similar to the red, green and blue dots on the front of




a color television  picture tube.)  The modified or false




color rendition comes into play when the exposed image on




the infrared film is processed.




     In the finished transparency, the scene objects (trees,




plants) producing infrared exposure, appear red in color,




while red and green objects produce green and blue images,




respectively.  The most important asset of this film is




its capability of recording the presence of various levels




of chlorophyll in plant growth.  The leaves on a healthy




tree will record as a bright red image rather than the usual




green.  Degraded foliage will approach a brownish red color.




The orange filter is used to keep all blue light from reach-




ing the film which would cause an unbalance in the normal red,




green, blue color balance.

-------
     The spectral sensitivity  data for each film and the optical

filter transmittance  curves  are  shown in Appendix A.

     Information regarding the development process for each type of

film is provided in Appendix B.

     The viewing angle  of the  KS-87 B framing cameras was 41°

centered about the aircraft's  nadir as shown below:

-------
     An infrared line scanner  (IRLS),  which records a thermal map

of an imaged area, completed the  array of airborne sensors used on

this mission.  The IRLS uses an infrared detector in an electroptic

system to record on film  the amount  of infrared energy detected in

the imaged area.  The effective focal  length of the IRLS is 1.15 inches

and the field of view is  120°  perpendicular to the line of flight.

     The three basic units  in  an  infrared reconnaissance set are

scanner optics, a detector, and a recording unit.  The scanner

collects the infrared emissions from the ground and reflects them

to a parabolic mirror.  The parabolic  mirror focuses the infrared

emissions onto the detector.   The detector converts the infrared

energy collected by the scanner into an electrical signal.  In

the recording unit the electrical signal is converted to visible

light through a cathode ray tube  which is then recorded on ordinary

black and white film.  The  diagrams  below depict the optical collection

system and the lateral field of view of the IRLS, respectively.

     Appendix C contains information pertinent to aerial  sensors


in respect to focal length,  angle of view,  and the effects  of  focal


length and altitude on scale and ground coverage.



VI.  FLIGHT PARAMETER DATA


     The flight parameter data specifies the  particular values of


the following aerial reconnaissance variables:


     a)  date of flight (s)


     b)  time of flight


     c)  direction-of-flight of each aircraft (target  area)

     d)  air speed of flight (knots)


     e)  aircraft altitude above ground level (AGL)

     f)  sensors to be used.


     The values of these parameters are given in  Table VI-1.

     The airspeed and low altitude flight restrictions were imposed



by the FAA Oakland Bay TRACON Center because of the heavy commercial




and general aviation traffic in the Bay area.  The jet aircraft



approach and departure patterns for the airports in this area, are



shown in Figure 3.

     The tidal phase differences at other numerous locations in the




Bay area are given in Table VIII-2.  To determine the time of high




water or low water at any station listed in this table there is given




in the columns headed "Differences, Time" the hours and minutes




to be added to or subtracted from the time of high or low water at




some reference station.  A plus (+) sign indicates that the tide at




the subordinate station is later than at the reference station and the




difference is added, a minus (-) sign that it is earlier and is subtracted.




For height differences, a plus (+) sign indicates that the difference




is added to the height at the reference station and a minus (-) sign




that it is subtracted.

IX.  RESULTS OF THE REMOTE SENSING DATA INTERPRETATIONS




     The San Francisco Bay Area was divided into four sections




and labeled A, B, C, and D.  These sections were covered by the




reconnaissance aircraft during the daylight hours on April 26,




27, 1972 and July 25, 26, 27, 1972.  Two late night missions




were flown on July 26, 27, 1972 over sixteen select targets.




These targets are the eight major municipal waste sources and




the eight major industrial waste sources in the Bay area.  They




are identified below and their respective locations are shown




in Figure 4.

     Each waste discharge/significant indication is discussed in




outline form in the next four sub-sections of this report.  The




location of each indication is depicted on the appropriate USGS 7.5




minute map by red numbers.  These numbers correspond to the paragraph




numbers found in the text or body of this report.  The indications




recorded during the April, July (daytime) and July nighttime missions




are identified as such.  If one of the above dates is not included




for a particular location (such as July night), then no indication




was recorded during flight.






San Francisco Bay Area - Section A




     This section covers the area from Pinole Point, in San Pablo




Bay, eastward through Suisun Bay to a point along the San Joaquin




River approximately 3.2 kilometers (2 miles east) of the City of




Antioch.  This area is shown in Figure 5.  The location of this sec-




tion is shown in Figure 1.




NOTE:  Indication numbers A-l through A-10 appear on Figure 6, the




Mare Island map.




A-l      April - The thermal imagery recorded a large thermal




                 plume around the tip of Pinole Point that ex-




                 tended eastward for approximately 2.14 kilometers




                 (7,000 feet).  It is shown in Figure 7.  Source of




                 the thermal outflow was not detected in either the




                 thermal or optical reconnaissance data.

A-8       April - An effluent of warm water was being discharged




                  through a concrete structure (4.6 meters wide




                  and extending 9.2 meters out into the water)




                  from a series of ditches originating within




                  the Union Oil Company.  This is shown in Figure




                  8.  This discharge produced no apparent dis-




                  coloration in the receiving Bay waters.




          July -  An identical indication was recorded.  The




                  thermal map is shown in Figure 10.




          "July Night" - A large thermal plume was generated by




                  this point of discharge.  It is shown in Figure 9.








A-9       April - This discharge was active at the time of flight.




                  It produced no discoloration in the Bay waters.




                  The thermal map, Figure 8, indicates that the




                  water temperature of this effluent was some-




                  what cooler than that of A-8.  This is shown




                  by the small tear-drop shaped thermal field




                  in Figure 8.  This was recorded at a point in




                  time approximately one hour prior to the crest




                  of low-high tide.  Figure 8 shows that the thermal




                  field was being carried toward the Davis Point




                  dock.

                                 36
         July -  The outfall was active at the time of flight.




                 The temperature of the discharge was nearly




                 equal to that of the Bay waters in this immedi-




                 ate area.  No thermal plume from this outfall




                 is seen in Figure 10.




        "July Night" - This outfall was discharging hot water




                 at the time of this night mission as shown in




                 Figure 9.  It was recorded approximately 0.5




                 hours after the crest of high-high tide in this




                 area.




A-10     April - This outfall, reportedly within the Union Oil




                 Company facility, was discharging warm water




                 at the time of flight.  This is shown by the




                 arrow on the far right-hand side in Figure 8.




                 A smaller tear-drop phenomenon, than that dis-




                 cussed above, was recorded in this immediate




                 area.




         July -  The outfall was also active during this mission.




                 The temperature of the effluent was close to that




                 of the receiving Bay waters.




        "July Night" - This outfall was discharging hot water at




                 the time of flight.  The thermal discharges,




                 labeled A-8, A-9, and A-10, combined to form a




                 large thermal field that extended 305 meters




                 (1,000 fee§ out into the Bay and 915 meters




                 (3,000 feet) northward to the pier at Davis Point.

-------
                                 37
                 Again, high-high tide had crested 0.5 hours




                 prior to the recording of the thermal map in




                 Figure 9.  The influx of water into this area




                 carried the thermal field northward or toward




                 the bottom of the page.




NOTE!  Indication numbers A-ll through A-22 appear on Figure 11, the




Benicia map.




A-ll     April - Characteristics of a subsurface discharge were




                 recorded at this location.  It produced no




                 apparent discoloration in the receiving water.




         July -  Same indication as April.




A-12     April - A ditch carrying a reddish-brown wastewater,




                 was discharging into the Carquinez Strait at




                 the time of flight.  This ditch, approximately




                 6.1 meters (20 feet) wide, exited from under




                 the railway tracks on the southern side of the




                 C&H Sugar Company facility and emptied into




                 the Strait along the eastern side of the




                 Carquinez Bridge as shown in Figure 11.  The




                 source(s) of the discharge could not be deter-




                 mined .




         July -  Identical indication was recorded.




        "July Night" - This ditch was discharging warm water at




                 the time of flight.  This is shown in Figure 9.

-------
                                38
A-13      April - At this particular location within the C & H




                  Sugar Company, two subsurface discharges were




                  active.




          July -  Water level characteristics at the time of




                  flight indicated the presence of the above




                  mentioned active outfalls and possibly a




                  third in the immediate area.




          "July Night" - The two outfalls were discharging a




                  hot effluent at the time of flight.  They are




                  shown in Figure 9.  The effluents were creating




                  a thermal plume 92 meters (300 feet) in a




                  length parallel to shore.




A-14      "July Night" - Evidence of a warm discharge was recorded




                  at this location.   Inspection of the daytime




                  optical imagery provided nothing to confirm




                  the presence of an outfall.  There were several




                  buildings south of this area across the rail-




                  way tracks.




A-15      April - An orange-brown substance was being discharged




                  through a small open ditch into the Strait.




          July -  No discharge present.




A-16      April - There was a moderate discharge from a small




                  shoreline indentation into Carquinez Strait




                  with no subsequent discoloration in the receiving




                  waters.  An STP was located in this immediate




                  vicinity.

-------
                                39
          July -  Identical indication recorded.




          "July Night" - The discharge was warm at this time of




                  flight as shown in Figure 12.




A-17      April - A possible discharge was located in this area.




                  No significant discoloration was seen in this




                  area.




          July -  Same indication as April.




          "July Night" - This waterway was quite warm as seen in




                  Figure 12.




A-18      April - An inactive outfall was observed at this location.




          July -  Identical indication.




A-19      "July Night" - A small thermal field or plume was de-




                  tected in this area (Figure 12) suggesting a




                  possible discharge.  It extended approximately




                  12 meters out from shore.




A-20      "July Night" - A small warm outflow was recorded in




                  this area, as shown in Figure 12.  The source(s)




                  could not be ascertained.  The resultant thermal




                  plume extended nearly 15 meters (50 feet) out from




                  shore.




A-21      April - An active outfall was creating a dark gray




                  plume.  The discoloration could be traced




                  back to an aeration pond.




          July -  The outfall was also active.  A black substance




                  was floating on the water in the area of this




                  outfall.

-------

-------
                                 40
A-22    "July Night" - A small warm thermal plume originating




                 at this point, had moved west along the shore




                 for 15 meters (50 feet) where it had cooled to




                 the ambient temperature of the Strait waters.




NOTE;  Indication numbers A-23 through A-35 appear on Figure 13 the




Port Chicago map.




A-23     April - This waterway was yellow-brown in color at the




                 time of flight.  There was no visible plume or




                 extended dispersion pattern in Carquinez Strait.




         July -  Same indication as April.




A-24     April - A green-brown substance was entering the Strait




                 from this ditch.  There was no appreciable plume




                 in the receiving water.




         July -  Identical indication.




A-25     April - The discharge from this waterway into Suisun Bay




                 was a gray-brown color.  A moderate sized plume




                 was generated in the Bay and flowed in a south-




                 westerly direction for 200 meters (650 feet)  be-




                 fore it dispersed sufficiently to lose its identity.




        "July Night" - This discharge was warm as indicated in




                 Figure 12.




A-26     April - A gray-brown discharge from this ditch entered




                 Suisun Bay creating a small plume that moved




                 in a southwest direction dissipating within




                 75 meters (245 feet).

                                41
          "July Night" - The discharge from this ditch was imaged




                  as being cooler than the ambient waters of Suisun




                  Bay.




A-27      April - The water in Pacheco Creek was a reddish-brown




                  color and did not create a plume as it entered




                  Suisun Bay.




          July -  Same indication as April.




A-28      April - An above-surface outfall was recorded at this




                  location.  There was no discharge at the time




                  of flight.




          July -  Identical indication.




A-29      "July Night" - Two outfalls, reportedly from the Phillips




                  Petroleum Company facility, were discharging hot




                  effluents at the time of flight.  They are shown




                  in Figure 14.  An enlarged view is in Figure 15.




A-30      "July Night" - Two discharges were entering Grayson




                  Creek from the STP as shown in Figure 16.  This




                  Figure overlaps the bottom of Figure 14.




A-31      April - An inactive outfall was recorded at this point.




          July -  Same indication as April.




A-32      April - The color of the water in this area of Suisun




                  Bay was gray-green at the time of flight.




          July -  No significant discoloration in this area.




         "July Night" - The waterway from this point upstream to




                  the ponds were quite warm as shown on Figure 14.

A-33       April - Exceptionally turbid water was entering the




                   Bay from these ditches.




A-34       April - There was a surface outfall at this location.




                   It was not discharging at the time of flight.




           July -  The outfall was not discharging.




A-35       April - The water in Hastings and Belloma Sloughs was




                   reddish-brown in color.  There was no measureable




                   plume in the Bay from these sloughs.




Note:  Indication numbers A-36 through A-40 appear on Figure 17,




       the Honker Bay map.




A-36       April - There was a dike across the mouth of this




                   geometric-shaped ditch network.  There was a




                   yellow-green substance in a ditch connecting




                   the ponds immediately east to the network.  No




                   discoloration was recorded in this network.




           "July Night" - This network was imaged as being quite




                   warm, shown in Figure 18.




A-37       April - There was a dark brown outflow from this ditch.




                   There was no measureable plume or dispersion




                   pattern in the Bay.




           July -  Same indication.

A-38       April - The outflow from these waterways was yellow-




                   brown in color and was high in turbidity.   No




                   measureable plumes were observed in the Bay




                   waters.




           July -  Same indication.




A-39       April - Two submerged outfalls were discharging under




                   pressure.  There appeared to be no discoloration




                   in the receiving waters.




A-40       April - A submerged outfall was discharging a dark brown




                   effluent which appeared to be a poorly treated




                   outflow from the adjacent STP.




           "July Night" - A warm discharge was causing a moderate




                   sized thermal plume as shown in Figure 18.




Note;  Indication numbers A-41 through A-57 appear on Figure 19,




       the Antioch North map.




A-41       July -  An active outfall was detected here.  There was




                   no discoloration or plume in the receiving water.




A-42       April - An outfall just located immediately above the




                   water surface was discharging a reddish-brown




                   colored water.  Sun reflection from the capillary




                   wave action in this area prevented the detection




                   of any plume.




           July -  The outfall was active and the plume extended out




                   into the slough 76 meters (250 feet) and 183 meters




                   (600 feet) down stream.

        "July Night" - This outfall was discharging at the




                 time of flight resulting in a small thermal




                 plume.  This is shown in Figure 20.




A-43     April - A dark gray-brown substance was being discharged




                 into the slough through a ditch originating




                 within the U.S. Steel Corporation complex.   There




                 was no significant discoloration in the receiving




                 water.




         July -  Same indication.




        "July Night" - The thermal imagery recorded a hot dis-




                 charge from the ditch as shown in Figure 20.




A-44     July -  An active outfall was discharging a gray-brown




                 effluent into the pond.  There appeared to  be




                 no discharge from the pond into the New York




                 Slough.




A-45    "July Night" - The pond, mentioned in A-44, was dis-




                 charging into the slough at the time of flight.




                 The water in the pond and in the effluent were




                 quite warm.  The point of discharge is shown




                 in Figure 20.




A-46     April - A large pipe was extending from the bank down to




                 the water.  It was not discharging at the time of




                 flight.




         July -  Same indication as April.




A-47     July -  At this location there was a small plume gray-




                 brown in color.  The probable source is a pond




                 behind the ditch.

A-48     April - There was a small amount of a yellow-brown out-




                 flow from this waterway.




         July -  Still a small flow but the color was reddish-brown.




A-49     April - The water in this boat repair area was quite




                 turbid.




         July -  Same indication as April.




A-50     April - There was a yellow-brown outflow from this waterway.




                 The small plume generated was dissipated rapidly in




                 the San Joaquin River.




         July -  There was no outflow.




A-51     April - There was a large volume of a turbid gray-yellow




                 being discharged into the river.  A measureable




                 plume was not generated.




         July -  Thirty meters (100 feet) inland from the bank




                 of the river, an above-surface outfall was dis-




                 charging a large volume of a reddish-brown waste-




                 water into the waterway.




        "July Night" - The waterway imaged as being hot.  The




                 water was moving into the river and then in an




                 easterly direction.  The plume extended approxi-




                 mately 15 meters (50 feet) out into the river.




                 This is shown in Figure 21.




A-52    "July Night" - A hot discharge was recorded at this




                 location.  There was no activity detected in




                 the daytime optical imagery.  This is shown in




                 Figure 21.

        "July Night" - A large hot plume was generated as shown




                 in Figure 23.  It extended nearly 275 meters




                 (900 feet) eastward along shore with respect to




                 the discharge point.  This is shown in Figure 23.




A-57     April - An active outfall from the eastern end of the




                 Contra Costa electric power plant.




         July -  Same indication.  Plume is shown in Figures 22




                 and 24.  Figure 24 was recorded one day after




                 Figure 22.




        "July Night" - A large hot plume was generated, as shown




                 in Figure 23.  It extended along the eastern




                 shore for nearly 1,070 meters (3,500 feet).




NOTE;  Indication number A-58 appears on Figure 25, the Jersey Island




7.5 minute map.




A-58     July -  A discharge conduit leading from three ponds was




                 discharging at this point.  There was no visible




                 discoloration.




        "July Night" - The thermal imagery, Figure 23, show the




                 three ponds in this area as being warm.  A dis-




                 charge conduit or ditch is easily seen carrying




                 the warm effluent from the western most pond to




                 the river.

San Francisco Bay Area - Section B




     Section B extends from Pinole Point southward along the eastern




shores of San Pablo Bay and San Francisco Bay to a point approximately




0.8 kilometers (0.5 miles) south of the San Francisco-Oakland Bay




Bridge.  This is shown in Figure 1 and Figure 26.




NOTE;  Indication number B-l appears on Figure 27, the Richmond map.




B-l      April - No discernable indication recorded.




         July -  A small volume of greenish water was flowing




                 through a ditch into San Pablo Bay from an




                 industrial area in Rheem.  The ditch contained




                 large surface mats of algae in its lower reaches.




NOTE;  Indication numbers B-2 through B-8 appear on Figure 28, the




San Quentin map.




B-2      April - The water flowing into San Pablo Bay from




                 San Pablo Creek was grayish brown in color.




         July -  No discoloration was recorded.  The temperature




                 of the Creek waters was somewhat cooler than




                 the Bay waters.




B-3      April - Moderate volume discharge through the ditch from




                 San Pablo S.D. Sewage Treatment Plant.  No dis-




                 coloration of Bay waters by the effluent was




                 recorded.  The effluent was not septic at time




                 of flight.




         July -  Effluent characteristics unchanged.

        "July Night" - The STP effluent was somewhat warmer




                 than the Bay waters,  as shown in Figure 29.




B-4      April - A large volume of wastewater was being discharged




                 from two adjacent locations within the Standard




                 Oil of California facility.  These are the main




                 outfalls of the facility.   The wastewater was




                 grayish brown in color and warmer than the re-




                 ceiving Bay waters.   The amount of dissolved




                 oxygen was low.




         July -  The large volume of discharged wastewater was




                 present during this mission but displayed a




                 grayish green color in addition to being warmer




                 than the receiving water.   The amount of dis-




                 solved oxygen in the wastewater was low.




        "July Night" - The outfall was quite warm and covered a




                 portion of the mud flat area.  This is shown in




                 Figure 29.




B-5      April - The three positions shown in Figure 28 are used,




                 for the most part, as overflow discharge locations.




                 Location "a" is a partially open ditch that originates




                 within the refining operational area.  It was  not




                 discharging at the time of flight.  Location "b" is




                 a partially open ditch that connects three holding




                 ponds to the Bay.  It was  discharging a small




                 volume of a dark-brown substance at the time of

                 flight.   Location "c" is also a partially open




                 ditch that connects the outflow of an API sepa-




                 rator with the Bay.  No flow was recorded during




                 this mission.   There was a significant amount  of




                 surface  algae  growth in the mud flats in the im-




                 mediate  vicinity of the outfall.




         July -  Locations "a"  and "b" were discharging small




                 volumes  of wastewater.  No apparent discoloration




                 in the receiving water was observed.   Location




                 11 c",  likewise, had algae growth in the adjacent




                 mud area.




B-6      April - No outfall indication.




         July -  A yellowish brown substance was being discharged




                 from a submerged outfall as indicated.




B-7      April - A pipe entered the water from the base of the




                 Standard Oil dock.  No discharge was  recorded.




         July -  No discharge recorded.




B-8      April - A submerged outfall, discharging a dark grayish




                 brown substance, was located between the two




                 access ramps of the Standard Oil dock.  The area




                 was surrounded by a portable surface skimmer.




                 It was containing nearly all of the effluent.




         July -  The outfall was not discharging.




NOTE;  Indication numbers B-9 through B-21 appear on Figure 27, the




Richmond map.

                                 51
B-9      April - A small effluent, positioned immediately above




                 water level, was recorded.   It produced no




                 discoloration in the canal  waters.




         July -  No outfall indication.




B-10     April - An outfall was discharging  a small  amount of




                 gray substance.   The outfall position was im-




                 mediately below the water's surface.




         July -  No discharge was recorded.




B-ll     April - A red pipe, 0.46 meters (1.5 feet)  in diameter,




                 entered the water.  No  discharge was  noted.




         July -  No discharge was recorded.




B-12     April - No discharge was recorded.




         July -  Water was being discharged  into the Channel.




                 It produced no discoloration in the receiving




                 water.




B-13     April - A pipe, 0.92 meters (3  feet) in diameter, con-




                 nected a circular holding pond with the Richmond




                 Inner Harbor.  The pond contained a dark, nearly




                 black, wastewater.  No  discharge was  recorded.




         July -  No discharge was recorded.   There was a seepage




                 area detected adjacent  to the circular pond  in




                 the location labeled as seepage in  Figure 30.




                 At the time of this mission, the seepage was not




                 reaching the waterway projecting northward from




                 the Harbor.

                                 52
B-14     April - There were a group of five ponds located




                 adjacent to the shore of the Richmond Inner




                 Harbor as shown in Figure 30.  Ponds 1, 2,




                 and 3 contained a bright orange liquid sub-




                 stance.   This waste was leaching to the Harbor




                 in the four areas of the figure identified




                 as a, b, c, and d.  The wastewater was dis-




                 charged into pond 1.  It then flowed to pond 2




                 and subsequently to pond 3 as indicated by the




                 respective arrows.  The orange seepage is




                 entering the small "c" waterway from under the




                 railroad bed.  Ponds 4 and 5 were also discharg-




                 ing to the rectangular shaped drainage ditch.




                 The wastewater entered the Harbor through point




                 "e."  Pond 4 had an orange patch on its left




                 side.  This in turn was seeping to the upper end




                 of the rectangular ditch.




         July -  Seepage to Harbor was also present.




B-15     April - No discharge from the Stege S.D. sewage treatment




                 plant was detected.




         July -  No discharge confirmed.




                 Information received from EPA, Region IX, indicates




                 that the effluent from this plant was re-routed




                 to the East Bay MUD in January 1971.

                               53






B-16       April - The water flowing from Cerrito Creek into




                   San Francisco Bay was slightly yellow-brown




                   in color.  It dispersed quickly in the ad-




                   jacent mud flats.




           July -  The water from this creek was even more yellow-




                   brown and quite turbid.  It, likewise, dispersed




                   quickly.




B-17       April - No discharge recorded.




           July -  A discharge was present at the time of flight.




                   Its location is sketched in Figure 31.  The land-




                   fill has changed significantly from that shown




                   in Figure 27.   The outfall produced only minor




                   discoloration in the water.




B-18       April - A reddish-brown discoloration was recorded in




                   the water at this location.  The source of this




                   effect could not be identified.  There was a




                   medium sized building situated near shore as




                   indicated by the * on Figure 27.




           July -  The reddish-brown effect was again present.  At




                   this time of flight, there was chlorophyllic




                   growth in the water and along shore as indicated




                   by the parentheses.




B-19       April - One long and one short dike containing a dark




                   grayish-brown water were discharging to the mud

                   Golden Gate Fields stable area.




           July -  Same indication as April.




B-20       April - A large concrete culvert was recorded at this




                   position.  It appeared to be a storm drain.




           July -  Same indication as April.




B-21       April - A reddish-brown substance was being discharged




                   from a concrete structure located by the arrow




                   on the map.  Small amounts of  oil was collecting




                   along shore and on the water in this triangular




                   area.  The source could not be determined.




           July -  The reddish-brown substance was again present.




                   There was no trace of oil in this area.




Note;  Indication numbers B-22 through B-27 appear on Figure 32,




       the Oakland West map.




B-22       April - The water in the immediate area of the concrete




                   culvert structure was yellow-gray in color.  The




                   source could not be determined.




           July -  Identical indication was recorded.




B-23       April - Water from a small ditch was being discharged




                   from the street into the mud flats with no  dis-




                   coloration.  Two buildings and a Holiday Inn




                   were located directly across the street.




           July -  Identical indication was recorded.

B-24     April - A grayish green substance was being discharged




                 through the rather large open conduit into the




                 Bay.  The source appeared to be within the




                 buildings as indicated in Figure 33.




         July -  Again, this discharge was present.   The waste-




                 water displayed an even more intense green color




                 during this mission.  Its color characteristics




                 suggest an organic waste.




B-25     April - A gray substance was present in the small ditch,




                 as indicated in Figure 33, at the time of flight.




                 The flow rate was quite small.  The receiving




                 water in the rectangular area, adjacent to
